3:19-21 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.
19. when the times of refreshing shall come—rather, "in order that the times of refreshing may come"; that long period of repose, prosperity and joy, which all the prophets hold forth to the distracted Church and this miserable world, as eventually to come, and which is here, as in all the prophets, made to turn upon the national conversion of Israel.
