John 14:15

If ye love me
Not that Christ doubted of the love of his disciples to him; but he argues from it to their observance of his precepts, seeing ye do love me; as all do who are born again, who have had any spiritual sight of him, of his glory, suitableness, and fulness; who believe in him, and have received from him; who have had his love shed abroad in their hearts, having enjoyed communion with him, and know the relation he stands in to them; these love him above all others, and all of him, and that belong to him, unfeignedly, and in the sincerity of their souls, as did the disciples; and since they professed to love, and did love him, as they ought to do, he exhorts them, saying,

keep my commandments:
Christ is Lord over his people, as he is the Creator and Redeemer of them, and as he is an head and husband to them, and as such he has a right to issue out his commands, and enjoin a regard unto them; and these are peculiarly "his", as distinct from, though not in opposition to, or to the exclusion of, his Father's commands; such as the new commandment of loving one another, and the ordinances of baptism, and the Lord's supper, which are to be observed and kept as Christ has ordered them, constantly, in faith, and with a view to his glory.
