We are encouraged by the tenor of this song, inasmuch that even great sins can know great forgiveness. It is thought that David is the penman, writing after his sin with Bathsheba. He cries from the great depths, even from the bottom of his anguished heart. But he is persuaded that even his sin could be forgiven, as he prays from a broken and contrite heart.
He does not wait passively for the Lord to answer, but actively in prayer and trusting in His word. God’s word promises forgiveness and redemption through the blood of a substitute. And though this truth was under types in the Old Testament, yet believers understood that God was the only One able to forgive sin through a sacrifice provided. Those who are Israelites indeed, that is the children of God, have always a lively hope in God’s forgiveness.
The chiefest of sinners, all sinners who comprise the election of grace, that trust in His mercy, are redeemed through precious blood. And so all Israel shall be saved and know redemption.
1 Lord, from the depths to thee I cried.
