Remembering the Mission

By Justin Jeppesen

Acts 1:8 reminds believers that the mission of God continues through Spirit-empowered witness. Discover how Pentecost renews our call to prayer, gospel proclamation, and mission to the nations.

Acts 1:8 – Pentecost and the Call to Spirit-Empowered Witness

Remember the mission. That first day of Bible Study Methods class as a college freshman changed everything. After careful study and observation of just one verse, a textbook became more than a book. Acts 1:8 became more than a verse. The Bible became more than familiar words on a page. Leaving class that day, the world looked different because the call of Christ looked different. The mission of God was no longer abstract. It was personal. Urgent. Global. Eternal. What follows are some key discoveries that have renewed my awareness of and participation in God’s mission.

Remember the Mission: Christian Witness to the Nations

“But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.” (Acts 1:8)

The first word matters. “But.” Jesus was responding to the disciples’ question about the kingdom. They were looking for immediate fulfillment. They were asking about Israel and were focused on timing, comfort, and restoration as they understood it. Yet Jesus redirected their vision. The kingdom of God was not merely earthly, political, or temporary. The kingdom of God would spread through transformed lives, through the power of the Holy Spirit, and through witnesses carrying the gospel to the nations.

The disciples asked, “Lord, will you…?” Jesus answered, “But you…”

That shift changes everything. The mission of God is not passive observation. It is prayerful, active participation. The disciples were not called to speculate about timing. They were called to witness. They were called to obedience. They were called to the nations.

The mission of God is not passive observation. It is prayerful, active participation.

And this mission did not begin in Acts 1:8. Throughout the gospels, Jesus clarified the mission again and again. In John, believers are sent just as the Father sent the Son. In Mark, the gospel is proclaimed to the whole creation. In Matthew, disciples are made through evangelism, baptism, and teaching. In Luke, repentance and forgiveness of sins are proclaimed to all nations. Then Acts 1:8 completes the picture: the mission will only be accomplished through the power of the Holy Spirit.

We are sent to everyone everywhere with a strategy, telling a message, and empowered for the task.

This is not merely a ministry for a few. This is the calling of every believer. The mission belongs to the Church. The task belongs to every follower of Christ. The question is not whether believers are called. The question is whether believers will obey.

Remember the Means: Holy Spirit Power

Acts 1:8 answers the question of means. How will the mission be fulfilled? Not through human strength. Not through programs or personality. But, “You will receive power when the Holy Spirit has come upon you.”

The power of the Holy Spirit is not optional. It is necessary.

Jesus called the Holy Spirit “the promise of the Father” (Luke 24:49). Because Christ died and rose again, believers receive the indwelling presence of the Holy Spirit. A God-sized mission requires God-sized power. The Holy Spirit is not a force. He is not an “it.” He is the third member of the Trinity, fully God, continually abiding with believers. The power cannot be separated from the person.

Notice also the word “receive.” The Holy Spirit is a gift of grace. The mission begins with grace and is sustained by grace. The Church does not manufacture spiritual power. The Church receives it. The Church depends upon it.

This is why prayer matters. In Acts 1, the disciples devoted themselves to prayer before the Spirit came. Prayer precedes empowerment, sustains witness, and aligns the Church with the heart of God. A prayer-less church cannot expect Spirit-empowered mission. The pattern throughout Acts is unmistakable: worship, prayer, dependence, witness, multiplication.

Prayer precedes empowerment, sustains witness, and aligns the Church with the heart of God.

Remember the Message: Believers Are Called to Witness

Then comes the message. “You will be my witnesses.”

A witness testifies to what they have seen and heard. A witness speaks the truth, pointing away from themselves and toward another. Christian witness is not ultimately about opinions, preferences, or personal success. It is about Jesus Christ—His death, His resurrection, His kingdom, His gospel.

To witness means that our life and lips proclaim the reality of Christ with authenticity and integrity.

When people hear you speak, do they hear Jesus? When people observe your lives, do they see Jesus? In Acts 4:13, people recognized that Peter and John “had been with Jesus.” That is the essence of witness. Spirit-filled people reflect the Savior they proclaim.

Yet witness also carries cost. The Greek word for witness is related to the word “martyr.” Jesus was preparing His disciples for suffering. The mission would move forward through persecution, hardship, sacrifice, and even death. Christian history confirms this reality. The apostles gave their lives as witnesses of Christ because they believed the gospel was worth everything.

And still the mission advanced.

Remember the Magnitude: Jerusalem, Judea, Samaria, the Ends of the Earth

Jesus then defined the magnitude of the mission: Jerusalem, Judea, Samaria, and the ends of the earth. This progression became the outline of Acts itself. The gospel spread from the city to the surrounding regions and ultimately toward the nations.

Yet this command was deeply cross-cultural from the beginning. Jerusalem was not the disciples’ hometown. Jesus was calling them beyond comfort and familiarity. He was calling them to people different from themselves. The mission of God has always been global because the heart of God has always been for the nations.

From Abraham onward, God blessed His people so that all peoples would be blessed. Israel was chosen to display the glory of God among the nations. The church is now sent with the gospel to everyone everywhere.

Acts tells the story. In Jerusalem, the disciples prayed and waited. The Spirit came. Thousands believed. Jews from every nation heard the gospel. Then persecution scattered believers into Judea and Samaria, and the word continued to spread. By Acts 13, the Holy Spirit called Paul and Barnabas to take the gospel to unreached places.

And the church still lives in the “ends of the earth” phase of Acts 1:8. The story is not finished. The task is not complete. Billions still have never heard the name of Jesus. Thousands of people groups remain unreached. Entire villages, neighborhoods, and nations remain without access to the gospel.

Yet remember that we, the Church, possess something greater than resources, strategies, or earthly influence. The Church has been given the Holy Spirit. Jesus promised power for witness. Jesus promised His presence. Jesus promised that every tribe, tongue, and nation would one day stand before the throne.

So, the church must recover a bigger vision.

Not a vision centered on comfort, preference, or self-preservation. A vision for the nations. A vision for kingdom restoration throughout the earth. A vision shaped by prayer, generosity, sacrifice, and urgency.

There is always more to observe in Acts 1:8. More to see. More to obey. More to surrender. The verse is not simply information for study. It is a summons to witness. A summons to dependence upon the Holy Spirit. A summons to the nations.

The mission continues.
