This sermon concludes the “Christmas on Mission” series by teaching from 3 John 5–8 that Christmas itself is God’s first mission, sending His Son, and therefore the church is called to send and support missionaries in a way worthy of God. Using the example of Gaius, the message emphasizes that a faithful sending church commits to three things: genuine friendship marked by love and effort, worship-driven support that treats missionaries as precious to God, and active partnership that recognizes believers as fellow workers for the truth.
