Psalm 133
Psalm 133 reminds us that unity in the gospel is a good thing to be celebrated. As we sing this song, we call on each other as Christians to unite together in submission to Christ, not in an earthly peace where we make room for sin and error, but a peace wrought by the Spirit. That is unity in the gospel.
1 Then after fourteen years I went up again to Jerusalem with Barnabas, taking Titus along with me.
