Mere unity or unanimity is not what Paul desires for his fellow Christians, but a spirit of unity patterned after the perfect model of Him whose whole purpose was to do, not His own will, but the will of Him who sent Him (John 6:38). This same mind that was in Christ Jesus must be in each of His followers (Phil. 2:5).

 Literally, “to think the same thing” (see on ch. 12:16). Paul is not praying for identity of opinion on inconsequential matters, but for a spirit of unity and harmony, in spite of differences of opinion.

 Compare the expressions, “the God of hope” (v. 13), “the God of peace” (Rom. 15:33; Phil. 4:9; 1 Thess. 5:23; Heb. 13:20), “the God of all comfort” (2 Cor. 1:3), “the God of all grace” (1 Peter 5:10).
