Philippians 2:1

The apostle proceeds in this chapter where he left off in the last, with further exhortations to Christian duties. He presses them largely to like-mindedness and lowly-mindedness, in conformity to the example of the Lord Jesus, the great pattern of humility and love. Here we may observe, I. The great gospel precept passed upon us; that is, to love one another. This is the law of Christ's kingdom, the lesson of his school, the livery of his family. This he represents (Phi 2:2) by being like-minded, having the same love, being of one accord, of one mind. We are of a like mind when we have the same love. Christians should be one in affection, whether they can be one in apprehension or no. This is always in their power, and always their duty, and is the likeliest way to bring them nearer in judgment. Having the same love. Observe, The same love that we are required to express to others, others are bound to express to us. Christian love ought to be mutual love. Love, and you shall be loved. Being of one accord, and of one mind; not crossing and thwarting, or driving on separate interests, but unanimously agreeing in the great things of God and keeping the unity of the Spirit in other differences. Here observe, 1. The pathetic pressing of the duty.
