When we talk about missions, we must begin where all true mission begins, with God Himself. Before we discuss strategy, geography, or calling, we must look to the One whose plan shapes our lives and directs history.

This is the central message of Ephesians. As you follow Paul’s argument through the letter, you quickly see how deeply theological it is, especially in the first three chapters. By “theological,” I mean theology proper: the study of God. Who is God? What is He like? What is He doing in His world? Ephesians pulls back the curtain and reveals the Father’s magnificent plan. The whole Trinity is at work, but Paul highlights the Father’s role in this redeeming purpose.

The entire book of Ephesians could be summarized this way:

God the Father has designed a Great Salvation through His Son and has revealed it in the Church, Christ’s body (Ephesians 1–3). Because of this, we must walk in a manner worthy of our Great God (Ephesians 4–6).

This is the foundation of missions: God has a plan, and He equips His people to accomplish it. Even more, we can be confident that His plan will succeed. One day—at the end of all things—people from every tribe, tongue, people, and nation will fall before King Jesus and worship Him (Revelation 5). That worship will never end.

Yet when we look at the world today—at people groups in Pakistan, Afghanistan, Indonesia, and beyond with no known believers—it can be hard to imagine how this plan will unfold. Still, I want to be part of this great harvest, and I believe many others do as well.

Thinking About God’s Plan and Our Role

If the first step in missions is to marvel at God’s plan, the second is to consider how we join that plan. God’s mission includes every believer. So how do we approach it?

How do I discern what God wants me to do?
Should I relocate to be part of this work?
And if “God can steer only a moving vessel,” where should I begin moving?

Then comes the matter of strategy. Is the place I’m considering truly strategic for gospel ministry? I know a young missionary who recently changed fields because he believed the first country did not need more church planters from the USA, while the second one did. Decisions like this are not small.

The truth is this: clear, biblical thinking is essential for effective cross-cultural ministry. Some missionaries stay incredibly busy yet accomplish little. The same can happen to those serving here in Zambia—or in Kenya, Malawi, or wherever you live.

Missions requires more than activity; it calls for thoughtful obedience rooted in God’s character and purposes.

Conclusion

Ephesians teaches us that God’s plan for the nations is vast, unstoppable, and grounded in His own glory. Our task is to understand this plan, worship the God who designed it, and step faithfully into the role He has given us. Whether we go, send, disciple, give, or pray, every believer has a part in this great story.

And the end of the story is certain: Jesus will be worshiped by all peoples.
