All believers possess the privilege of participating with Christ in His mission to advance His gospel to the ends of the earth. Some, like Paul, are sent by God to proclaim the gospel on the front lines. Others, such as the believers in Philippi, are called and equipped by God to sustain gospel ministry in other ways. In this lecture, Dr. Lawson examines the Philippian believers’ significant role in Paul’s ministry, and he invites believers today to hold nothing back in supporting, equipping, and encouraging those who are on the front lines spreading the good news of Jesus Christ to people of all nations, tribes, and tongues.
