Ephesians 5:1

Here we have the exhortation to mutual love, or to Christian charity. The apostle had been insisting on this in the former chapter, and particularly in the last verses of it, to which the particle therefore refers, and connects what he had said there with what is contained in these verses, thus: "Because God, for Christ's sake, has forgiven you, therefore be you followers of God, or imitators of him;" for so the word signifies. Pious persons should imitate the God whom they worship, as far as he has revealed himself as imitable by them. They must conform themselves to his example, and have his image renewed upon them. This puts a great honour upon practical religion, that it is the imitating of God. We must be holy as God is holy, merciful as he is merciful, perfect as he is perfect. But there is no one attribute of God more recommended to our imitation than that of his goodness. Be you imitators of God, or resemble him, in every grace, and especially in his love, and in his pardoning goodness. God is love; and those that dwell in love dwell in God and God in them. Thus he has proclaimed his name, Gracious and merciful, and abundant in goodness.
