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.

John 14:15 In-Context

13 And I will do whatever you ask in my name, so that the Father may be glorified in the Son.

14 You may ask me for anything in my name, and I will do it.

15 “If you love me, keep my commands.

16 And I will ask the Father, and he will give you another advocate to help you and be with you forever—

17 the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you.
