I recently heard a sermon on Galatians 5 and 6. The pastor noted how the fruit produced by the tree isn’t for the tree, but is meant to serve others.
This mirrors the heart of God, who for our sake, made him who knew no sin to be sin, so in him, we might be the righteousness of God (2 Cor. 5:21).
Jesus came not to be served but to serve, and to give his life as a ransom for many (Mark 10:45).
