What the Book of Acts tells us about missions

The early church literally wrote the book on how to spread the gospel, reach across cultures, establish churches, and work through conflict. What can we learn from the text in Acts and also from reading between the lines? Is this first-century model readily transferrable to 21st century evangelism? Is our approach to missions grounded in scripture or has it evolved over time? Join this in-depth study and discussion as we refine our perspective on missions. 

Speaker: Arlan Miller

TBD - likely something related to church history and missions and/or persecution or apologetics.

Several interesting topics are still being explored with potential speakers. Please check back later for more details.

Speaker: TBD

Caring for our missionaries (for active and prospective Mentors and Advocates)

This session is for those interested in providing purposeful missionary care. While primarily designed towards active missionary mentors and advocates, those interested in potential opportunities to serve in missionary care are also welcome to register. We will discuss what has worked, what has not worked, and ideas for developing church support further. The workshop will be interactive and practical.

Speaker: Kirk Plattner

Rep Meeting

This session is specifically for HarvestCall Representatives. More information on this session will be coming later, but we expect this time to include providing important updates, questions & answers, and a time of idea sharing.

Speakers: TBD

Back to the Schedule.

Main Sessions

Held in the church assembly room, these are plenary sessions, meaning they are broad interest topics intended for everyone.

Living as sent people

Jesus said, “As thou hast sent me into the world, even so have I also sent them into the world” John 17:18. Was Jesus speaking only of his disciples or of us all? Learn what the Holy Spirit has to say about this question through the writers of the New Testament and how his presence and gifts enable us do life as “sent”  people regardless of our occupation or where we live.

Speaker: John Huber

"Because you came, I met Jesus"

When you look at all the time, effort and money that goes into missions, you may sometimes wonder, “Is it worth it?” We believe it is making an eternal difference for many. These speakers will share how grateful they personally are that as a result of Apostolic Christian outreach, they have been called out of darkness and into Jesus’ marvelous light.

Speaker: Gloria Gonzalez and TBD

Our missionary experience

Listen to the perspectives of those currently serving on the mission field in Haiti. Hear about their struggles and joys and ways you can support them in this work.

Speakers: Les & Christine Kaeb

Why is sharing the gospel so difficult?

Admit it. For most of us, the idea of sharing our faith with a stranger gives us cold sweats. Even talking about Jesus to people we know can be uncomfortable. Why is that, and what are ways to overcome this fear and reluctance? While not all of us have the gift of evangelism, we can all learn how to be a more effective witness — and to do so with less stress.

Speaker: Brad Metz

Back to the Schedule.

Ministry Update Breakouts

Find out what God is doing through the various ministries operating under HarvestCall. Choose the two that most interest you.

A spiritual Lifeline in Haiti

Many people are aware that HarvestCall’s Lifeline program builds houses and provides a medical clinic for Haitians in northern Haiti. But through that, God opened a door to assist with the spiritual development of Bethel Church leaders and help reach many for Christ. Hear how from this Bethel Church pastor.

Speaker: Pastor Nathan Dieudonne

Church planting and bolstering update

Curious about what is being done to start new churches and support our small congregations? In this breakout, you’ll hear about progress and opportunities in current bolstering efforts and how the Church Establishment Committee of HarvestCall is working with the Elder Body to explore potential locations for new congregations as together we wait upon the Lord to open doors.

Speaker: TBD

Healing souls at Hospital Lumiere

All hospitals diagnose and treat medical conditions, but the ultimate goal of Hospital Lumiere is to see people be reconciled to God — in additional to healing of the body. Find out how the gospel is never secondary in this medical mission, as told by the hospital’s chaplain.

Speaker: Pastor Smarth Etheard

Aiding the elderly and enabling the youth in Eastern Europe

The Brethren in Eastern Europe have gone through much persecution and hard times. Hear how these hard times and a broken communist society have affected the believers and how HarvestCall is trying to understand their situation and work beside them to provide opportunities for the youth to provide for and teach their families.

Speaker: Christopher Indermuhle

Haiti Dairy

Description coming soon…

Speaker: TBD

Ministering in Mexico

Description coming soon…

Speaker: Gloria Gonzalez

Topical Breakouts

The hardest part will be choosing the one you most want to attend, because sadly, there isn’t time in the day to repeat these.

Lessons learned from early AC evangelism

Our early Apostolic Christian church was phenomenally successful at evangelism and church planting, in Europe and America. While it was a unique time in history, we can learn things from their success and apply them to our outreach today.

Speaker: Fred Witzig

What is a culturally relevant gospel?

Ok — trick question. We shouldn’t try to make the gospel “culturally relevant.” It is already a perfectly relevant gospel for all times and ages — and it is unchangeable. But we DO need to think about how to present it in a culturally relevant way. Finding that balance (or . . .  managing that tension) can be difficult and it’s easy to feel pressure one way or the other. Let’s examine scripture to find the right approach.

Speakers: Nick Gutwein

The challenges of missionary reentry

Coming back to the USA after living in a foreign country as a missionary is more difficult than you might think. Find out what missionaries experience on re-entry and how we as a church can better support this transition.

Speaker: Scott & Mandy Yordy

Making yourself ready and available

What should we be doing in our daily lives to cultivate a willingness to be used for missions and to be prepared in case we do feel the call? And remember — that call could just be to reach out to our next door neighbor.

Speaker: Matt Knapp

How to help without hurting

Our attempts to help the poor sometimes lead to unintended consequences that can be damaging to everyone involved. Join this discussion group to share examples of how you’ve seen this play out in your efforts to help others and learn how to more effectively help without hurting.

Facilitator: Paul Streitmatter

Back to the Schedule.

Discussion Groups

 Interactive discussions in a small group format. Choose the two topics you are most interested in and come ready to participate! 

Simple methods for presenting the gospel

Knowing some practical techniques can help us overcome our fear of sharing with others. Learn about some great spiritual conversation starters and helpful props for explaining the gospel from our facilitator and other participants.

Facilitator: Brad Metz

Things we did to help our children understand the gospel

We all desire that our children walk in truth. We can learn from each other, especially when it comes to parenting and the all important task of imparting truth to our children. We must be intentional when it comes to helping our children understand the revelation and teachings of Christ. As Deuteronomy 6:6,7 says, “And these words which I command thee this day, shall be in thy heart; And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou riseth up.” We want to encourage one another in this all-important responsibility!

Facilitator: Ron & Edie Bollier

Helping new people feel welcome and integrate into our church

Walking through the doors of an AC church for the first time can be an intimidating culture shock for some people. Find out ways to alleviate that discomfort and help people feel welcome and begin to fit in. This issue isn’t just for the first few visits. It actually can get harder after a new person becomes a member.

Facilitator: Fred Janssen

How God can use your suffering to help others

In this world we experience disappointment, loss, and hardship. Often we wonder why. Why, when it seems like we would be so much more effective to the Lord without our bumps and bruises. In this session, explore how God can use us because of our wounds (not in spite of them) and how our response to suffering can bring hope to a broken world.

Facilitator: Amber Miller

Does everyone have a responsibility to share the gospel?

Some of us read the list of roles in Eps 4:11 and say “That’s not me.” So if we are not an apostle, prophet, evangelist, pastor, or teacher but as just an “average Christian” what is our responsibility when it comes to evangelism? Let’s discuss, roles, gifts, and Christ’s commands.

Facilitator: John Huber

Ways the church can respond to the drug epidemic

Drug abuse is no longer just a big-city problem. Meth and heroine addictions are ravaging the rural communities where many of us live. How should we as individual Christians and collectively as a church in or near an affected community respond to this? Let’s discuss ideas and share experiences.

Facilitator: Aaron Plattner

How to tell if you are really being called to the mission field

What is a calling to be a missionary? How do you discern whether or not you are being called? This session will be focused on how to think about calling and a discussion of the necessary ingredients. The discussion will review a biblical framework for calling and how to have a right outlook on discernment and stepping forward in faith.

Facilitator: Kirk Plattner

Reaching international college students in your community

Universities bring “the ends of the earth” right to our communities. Come learn and share practical ways to reach out and share Christ with this diverse — and often very receptive — audience.

Facilitator: Amy Mammadov

Help! My child wants to be a missionary

Sure, we support sending missionaries. Just let it be someone else’s child who goes, right? If you have a child who may be feeling the call to go, it can stir up many conflicting emotions as parents. This session will help you process those, answer some of your questions, and hopefully give you the confidence to trust God through this situation.

Speaker: TBD

Blessings and challenges of small church living

Ever wonder what it would really be like to attend a small church? And what is it like when suddenly several new families move in? Do increased numbers increase gospel-spreading effectiveness or just bring new challenges to the local body? Hear the story from those who’ve been through it in St. Louis and Austin and bring your questions.

Facilitator: TBD

Creative ideas for supporting missionaries (on the field and in re-entry)

Each of us are called to participate in The Great Commission. If you have not been sent to “proclaim & serve” away from your home, then you are a “sender” and your role is vital! In this discussion group we will explore the importance of the “sending role” and share creative ideas on how to better support our missionaries as they serve on the field as well as their re-entry back home.

Facilitator: Klint & Sarah Fiechter

Redeployment vs retirement

Come and discuss the opportunities to redeploy your skill sets, gained over a career, into the mission fields that are so ripe for harvest. We’ll visit about the call to redeploy, opportunities that exist, discerning God’s will, business as mission, and the rewards of redeployment versus retirement. God is such a faithful employer!

Facilitator: Stephen Baner

Sharing ways to embrace a culture of outreach and discipleship

In Matthew 28:19-20, we’re called to spread the gospel, baptize and then teach to “observe all things” pertaining to Christian life. Come prepared to brainstorm and share what you are doing to impact our church’s faithfulness in fulfilling the 4-Pillar mission to reach the unchurched and then disciple them with sound doctrine. Ideas and thoughts gathered will be shared with others who desire to be more effective in the Lord’s work.

Speaker: TBD

Pray for missionaries

Join us for a time of specific, focused prayer for our Apostolic Christian brothers and sisters serving in the mission field. We will take turns lifting them up to the Lord.

Facilitator: Jonathan Hodel

The role of fasting and prayer in missions

Some would say that trying to reach others for Christ without prayer and fasting is like driving a car without wheels: it just doesn’t go very well. Let’s discuss how we can support our missions with focused, intercessory prayer and examine the role fasting can play in orientating our hearts toward God.

Facilitator: John & Jill Bradle

Bible Distribution: a mission field close to home

HarvestCall has recently commissioned a new initiative to equip, empower, and assist our local churches and individuals to spread the gospel of Christ through the distribution of Bibles and other biblical resources. In this session, we will discuss improvements and developments already being made by HarvestCall as well as give you the opportunity to begin distributing Bibles in your community.

Facilitator: Wayne Laubscher

Using your Spanish language skills for missions

Description coming soon…

Facilitator: TBD

Your donation to HarvestCall: where it goes and ways to give

Does HarvestCall really need donations? How much of what you give actually goes to ministry? Are there tax advantages with certain types of giving? We’ll review our HarvestCall ministries and the funding required to support them and discuss giving options that may save taxes in light of the higher standard deduction per the new tax law. We’ll also take your questions about planned giving.

Facilitator: Nile Bucher
