And if we know that he hear us - That is, if we are assured of this as a true doctrine, then, even though we may not "see" immediately that the prayer is answered, we may have the utmost confidence that it is not disregarded, and that it will be answered in the way best adapted to promote our good. The specific thing that we asked may not indeed be granted, (compare Luke 22:42; 2 Corinthians 12:8-9), but the prayer will not be disregarded, and the thing which is most for our good will be bestowed upon us. The "argument" here is derived from the faithfulness of God; from the assurance which we feel that when he has promised to hear us, there will be, sooner or later, a real answer to the prayer.

We know that we have the petitions ... - That is, evidently, we now that we "shall" have them, or that the prayer will be answered. It cannot mean that we already have the precise thing for which we prayed, or that will be a real answer to the prayer, for

(a) the prayer may relate to something future, as protection on a journey, or a harvest, or restoration to health, or the safe return of a son from a voyage at sea, or the salvation of our souls - all of which are "future," and which cannot be expected to be granted at once; and,

(b) the answer to prayer is sometimes delayed, though ultimately granted. There may be reasons why the answer should be deferred, and the promise is not that it shall be immediate. The "delay" may arise from such causes as these:

(1) To try our faith, and see whether the blessing is earnestly desired.

(2) perhaps it could not be at once answered without a miracle.

(3) it might not be consistent with the divine arrangements respecting others to grant it to us at once.

(4) our own condition may not be such that it would be best to answer it at once.

We may need further trial, further chastisement, before the affliction, for example, shall be removed; and the answer to the prayer may be delayed for months or years. Yet, in the meantime, we may have the firmest assurance that the prayer is heard, and that it will be answered in the way and at the period when God shall see it to be best.

And if we know that he hear us - Seeing we are satisfied that he hears the prayer of faith, requesting the things which himself has promised; we know, consequently, that we have the petitions - the answer to the petitions, that we desired of him; for he cannot deny himself; and we may consider them as sure as if we had them; and we shall have them as soon as we plead for and need them. We are not to ask to-day for mercy that we now need, and not receive it till to-morrow, or some future time. God gives it to him who prays, when it is needful.

And if we know that he hear us,.... As it may be assured he does hear and answer all such persons that ask according to his will:

whatsoever we ask, we know, or are assured,

that we have the petitions that we desired of him: for as it is the nature of that holy confidence, which believers have in God, to believe whatever they ask according to his will, in general, shall be grappled, so every request in particular; yea, before the mercy desired, or the favour asked for is conferred, they are as sure of having it in God's own time and way, as if they now had it in hand and fact.

Whatsoever we ask

The whole phrase is governed by the verb hear. If we know that He heareth our every petition.

And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.

5:15 If we know that he heareth us. Hear us with open ears. Then we may know that we have what we ask. It will be granted.

5:15 We have - Faith anticipates the blessings. The petitions which we asked of him - Even before the event. And when the event comes, we know it comes in answer to our prayer.

15. hear-Greek, "that He heareth us."

we have the petitions that we desired of him-We have, as present possessions, everything whatsoever we desired (asked) from Him. Not one of our past prayers offered in faith, according to His will, is lost. Like Hannah, we can rejoice over them as granted even before the event; and can recognize the event when it comes to pass, as not from chance, but obtained by our past prayers. Compare also Jehoshaphat's believing confidence in the issue of his prayers, so much so that he appointed singers to praise the Lord beforehand.

5:13-17 Upon all this evidence, it is but right that we believe on the name of the Son of God. Believers have eternal life in the covenant of the gospel. Then let us thankfully receive the record of Scripture. Always abounding in the work of the Lord, knowing that our labour is not in vain in the Lord. The Lord Christ invites us to come to him in all circumstances, with our supplications and requests, notwithstanding the sin that besets us. Our prayers must always be offered in submission to the will of God. In some things they are speedily answered; in others they are granted in the best manner, though not as requested. We ought to pray for others, as well as for ourselves. There are sins that war against spiritual life in the soul, and the life above. We cannot pray that the sins of the impenitent and unbelieving should, while they are such, be forgiven them; or that mercy, which supposes the forgiveness of sins, should be granted to them, while they wilfully continue such. But we may pray for their repentance, for their being enriched with faith in Christ, and thereupon for all other saving mercies. We should pray for others, as well as for ourselves, beseeching the Lord to pardon and recover the fallen, as well as to relieve the tempted and afflicted. And let us be truly thankful that no sin, of which any one truly repents, is unto death.
