1 Juan 5:15

In the latter, in that, or somewhat equivalent, or better; for if he determine that thing to be best for us, all circumstances considered, we shall have it; if he determine otherwise, (supposing we pray according to his will), we desire it not: for every one intends good to himself, when he prays for any thing, not hurt. And God answers his children according to that general meaning of their prayers, not always according to the particular (which may be often a much mistaken) meaning. According whereto, supposing the thing would be really and in truth hurtful, (and God’s judgment is always according to truth), they constructively pray to be denied it; and the denial is the equivalent, nay, the better thing than what they particularly prayed for; and so they truly have their petitions: see 1 John 3:22. Nor can any be understood to pray according to God’s will as the rule, if it be not to his glory as the end, as the order and connexion of petitions shows in that admirable platform prescribed by our Lord himself. And is it possible to be the sense of any one that hath a sincere heart in prayer, that God would gratify him against himself? Therefore that latitude allowed the apostles, John 14:13,John 14:14; John 15:16; John 16:23, &c., must be understood to respect the service of the Christian interest, and is to be limited thereby, as some of the expressions show.
