Observe here, 1. An high and honorable privilege supposed to be claimed, and that is union with Christ, and abiding in him; he that saith he abideth in him. The abiding in Christ is a great privilege, and the true and real Christian doth truly and really abide in Christ.
Observe, 2. A great and important duty belonging to all those that do abide in Christ, and that is to walk as Christ walked; to set his example daily before them, and to be continually correcting and reforming of their lives by that glorious pattern. Every Christian is bound to an imitation of Christ, under penalty of forfeiting his claim to Christ; for no claim to Christ is or can be valid without a careful imitation of him. The temper of our minds, and the actions of our lives, must be a lively transcript of the mind and life of the holy and innocent Jesus; we must be like him, or we can never love him, nor hope another day to live with him.
