‘Now the God of patience and of comfort grant you to be of the same mind one with another according to Christ Jesus, that with one accord you may with one mouth glorify the God and Father of our Lord Jesus Christ.'
The source of this patient endurance and encouragement obtained through the Scriptures is in fact God, for He is the God of patient endurance and encouragement (comfort). And Paul prays that He, as such a God might grant to them to be of the same mind one with another, giving them patient endurance and encouragement, thereby enabling them to bear with each other's weaknesses and to demonstrate a unity that results from consideration towards one another, ‘in accordance with Christ Jesus', that is, by following His example and being like Him.
And the hoped for consequence is that they might in full accord and speak as one as they glorify the God and Father of our LORD Jesus Christ. Jesus Christ laid great emphasis on the need for such unity. It was to be the wonder of the world as they said, ‘see how these Christians love one another' (John 13:34-35; John 15:12; John 17:21-23). It was a result worth making sacrifices for. The aim was so that they would concentrate on what was really important, the united worship of God and the bringing home to the world of the glory of God and the glory of Christ.
