The gospel partnership of Johann Gerhard Oncken and Charles Haddon Spurgeon illustrates the heart of missions advancing through the local church. Drawing from Luke 24, Acts 13, and 3 John emphasize that missions involves proclaiming the gospel of Christ's suffering and resurrection, equipping disciples, and establishing churches, supported by the collective efforts of the church community. Through the biographical illustration of Johann Gerhard Oncken, the sermon highlights the importance of intentionality, perseverance, and partnership in spreading the gospel, ultimately urging listeners to actively participate in God's work of extending His grace to the nations and fulfilling the biblical mandate to share the message of salvation.
