Acts 3:19

(1.) That they should have the pardon of their sins; this is always spoken of as the great privilege of all those that embrace the gospel (v. 19): Repent, and be converted, that your sins may be blotted out. This implies, [1.] That the remission of sin is the blotting of it out, as a cloud is blotted out by the beams of the sun (Isa 44 22), as a debt is crossed and blotted out when it is remitted. It intimates that when God forgives sin he remembers it no more against the sinner; it is forgotten, as that which is blotted out; all the bitter things written against the sinner (Job 13 26) are wiped out as it were with a sponge; it is the cancelling of a bond, the vacating of a judgment. [2.] That we cannot expect our sins should be pardoned unless we repent of them, and turn from them to God. Though Christ has died to purchase the remission of sin, yet, that we may have the benefit of that purchase in the forgiveness of our sins, we must repent, and be converted: if no repentance, no remission. [3.] Hopes of the pardon of sin upon repentance should be a powerful inducement to us to repent. Repent, that your sins may be blotted out: and that repentance is evangelical which flows from an apprehension of the mercy of God in Christ, and the hopes of pardon. This was the first and great argument, Repent, for the kingdom of heaven is at hand. [4.] The most comfortable fruit of the forgiveness of our sins will be when the times of refreshing shall come; if our sins be forgiven us, we have now reason to be of good cheer; but the comfort will be complete when the pardon shall be allowed in open court, and our justification published before angels and men—when whom he has justified, them he glorifies, Rom 8 30. As now we are the sons of God (1 John 3 2), so now we have our sins blotted out; but it doth not yet appear what are the blessed fruits of it, till the times of refreshing shall come. During these times of toil and conflict (doubts and fears within, troubles and dangers without) we cannot have that full satisfaction of our pardon, and in it, that we shall have when the refreshing times come, which shall wipe away all tears.

Verses 19-21 The absolute necessity of repentance is to be solemnly charged upon the consciences of all who desire that their sins may be blotted out, and that they may share in the refreshment which nothing but a sense of Christ's pardoning love can afford. Blessed are those who have felt this. It was not needful for the Holy Spirit to make known the times and seasons of these dispensations. These subjects are still left obscure. But when sinners are convinced of their sins, they will cry to the Lord for pardon; and to the penitent, converted, and believing, times of refreshment will come from the presence of the Lord. In a state of trial and probation, the glorified Redeemer will be out of sight, because we must live by faith in him.
