Repent, therefore - Here we may remark:

(1) That Simon was at this time an unconverted sinner.

(2) that the command was given to him "as such."

(3) that he was required to "do the thing"; not to wait or seek merely, but actually to repent.

(4) that this was to be the "first step" in his conversion. He was not even directed to "pray" first, but his first indispensable work was to "repent"; that is, to exercise proper sorrow for this sin, and to "abandon" his plan or principle of action.

And this shows:

(1) that all sinners are to be exhorted to "repent," as their first work. They are not to be told to "wait," and "read," and "pray," in the expectation that repentance will be "given" them. With such helps as they can obtain, they are to "do the thing."

(2) prayer will not be acceptable or heard unless the sinner comes "repenting"; that is, unless he regrets his sin, and "desires" to forsake it. Then, and then only, will he be heard. When he comes "loving" his sins, and resolving still to practice them, God will not hear him. When he comes "desirous" of forsaking them, grieved that he is guilty, and "feeling" his need of help, God will hear his prayer. See Isaiah 1:15; Micah 3:4; Proverbs 1:28; Psalm 66:18.

And pray God - Having a "desire" to forsake the sin, and to be pardoned, "then" pray to God to forgive. It would be absurd to ask forgiveness until a man felt his need of it. This shows that a sinner "ought" to pray, and "how" he ought to do it. It should be with a desire and purpose to forsake sin, and in that state of mind God will hear the prayer. Compare Daniel 4:27.

If perhaps - There was no certainty that God would forgive him; nor is there any evidence either that Simon prayed, or that he was forgiven. This direction of Peter presents "another" important principle in regard to the conduct of sinners. They are to be directed to repent; not because they have the "promise" of forgiveness, and not because they "hope" to be forgiven, but because sin "is a great evil," and because it is "right" and "proper" that they should repent, whether they are forgiven or not. That is to be left to the sovereign mercy of God. they are to repent of sin, and then they are to feel, not that they have any claim on God, but that they are dependent upon Him, and must be saved or lost at His will. They are not to suppose that their tears will purchase forgiveness, but that they lie at the footstool of mercy, and that there is hope - not certainty - that God will forgive. The language of the humbled sinner is:

"Perhaps he will admit my plea,

Perhaps will hear my prayer;

But if I perish I will pray,

And perish only there.

Repent therefore of this thy wickedness - St. Peter did not suppose his case to be utterly hopeless; though his sin, considered in its motives and objects, was of the most heinous kind.

If perhaps the thought of thine heart may be forgiven thee - His sin, as yet, only existed in thought and purpose; and therefore it is said, if perhaps the thought of thine heart may be forgiven.

Repent therefore of this thy wickedness,.... For a great piece of wickedness it was, to offer money for the gift of the Holy Ghost, and to imagine, that could be purchased with money; and what made the wickedness still greater was, the evil design he had in this, to advance himself in opposition to Christ and his apostles, as he afterwards did; and when the apostle puts him upon repentance, his view is to show the heinousness of his crime, the need he stood in of repentance, and that without it, his case must be miserable:

and pray God, if perhaps the thought of thine heart may be forgiven thee; though he was in a state of nature, the apostle exhorts him to the duty of prayer; for prayer is a natural duty, and binding upon all men, though none but a spiritual man can perform it in a spiritual way: and though this sin of Simon's was a very heinous one, and came very near unto, and looked very much like the sin against the Holy Ghost, yet it was not the unpardonable one; it might be pardoned by the grace of God, and through the blood of Christ; and therefore Peter, who wished his salvation and not his damnation, put him upon prayer for it; which was possible, though difficult, but not certain: the apostle says not this, as doubting; if it was a case wholly to be despaired of, then he would not have directed him to the means; and yet the wickedness was so horribly great, and he in such a wretched hardened state, that there was no great hope or expectation of his repentance, and so of the application of pardon to him: however, this advice was not given ironically: Peter was too grave and serious to speak sarcastically, or break a jest upon a man in such circumstances; whom no doubt he heartily pitied, though he abhorred his sin: the Syriac version renders it, "the deceit of thine heart": and the Ethiopic version, "the evil thought of thine heart"; and such it was.

If perhaps

The doubt suggested by the heinousness of the offence.

Thought (ἐπίνοια)

Only here in New Testament. Lit., a thinking on or contriving; and hence implying a plan or design.

{10} Repent therefore of this thy wickedness, and pray God, if perhaps the thought of thine heart may be forgiven thee.

(10) We must hope well even for the vilest sinners, as long as and as much as we can.

8:22 Repent therefore of this. Observe that Peter does not bid him to repent of his sins, but of this one great sin.

If perhaps the thought of thine heart. This one sin is so great that Peter seems doubtful whether it will be forgiven, even on repentance and prayer.

8:22 Repent - if perhaps the thought of thy heart may be forgiven thee - Without all doubt if he had repented, he would have been forgiven. The doubt was, whether he would repent. Thou art in the gall of bitterness - In the highest degree of wickedness, which is bitterness, that is, misery to the soul; and in the bond of iniquity - Fast bound therewith.

22. Repent . pray . if perhaps the thought of thine heart may be forgiven-this expression of doubt being designed to impress upon him the greatness of his sin, and the need of alarm on his part.

8:14-25 The Holy Ghost was as yet fallen upon none of these coverts, in the extraordinary powers conveyed by the descent of the Spirit upon the day of Pentecost. We may take encouragement from this example, in praying to God to give the renewing graces of the Holy Ghost to all for whose spiritual welfare we are concerned; for that includes all blessings. No man can give the Holy Spirit by the laying on of his hands; but we should use our best endeavours to instruct those for whom we pray. Simon Magus was ambitious to have the honour of an apostle, but cared not at all to have the spirit and disposition of a Christian. He was more desirous to gain honour to himself, than to do good to others. Peter shows him his crime. He esteemed the wealth of this world, as if it would answer for things relating to the other life, and would purchase the pardon of sin, the gift of the Holy Ghost, and eternal life. This was such a condemning error as could by no means consist with a state of grace. Our hearts are what they are in the sight of God, who cannot be deceived. And if they are not right in his sight, our religion is vain, and will stand us in no stead. A proud and covetous heart cannot be right with God. It is possible for a man to continue under the power of sin, yet to put on a form of godliness. When tempted with money to do evil, see what a perishing thing money is, and scorn it. Think not that Christianity is a trade to live by in this world. There is much wickedness in the thought of the heart, its false notions, and corrupt affections, and wicked projects, which must be repented of, or we are undone. But it shall be forgiven, upon our repentance. The doubt here is of the sincerity of Simon's repentance, not of his pardon, if his repentance was sincere. Grant us, Lord, another sort of faith than that which made Simon wonder only, and did not sanctify his heart. May we abhor all thoughts of making religion serve the purposes of pride or ambition. And keep us from that subtle poison of spiritual pride, which seeks glory to itself even from humility. May we seek only the honour which cometh from God.
