The Healing in the Waiting
The depths (maʿămaqqîm) is an image of dangerous waters (cf. Ps 69:2[3]) that pictures chaos or overwhelming disaster
The psalmist was not a cynic, nor had he given up on his relationship with God. On the contrary, he was convinced that his ties to God were so firm that he could call on God for help in the hour of deepest need, when he was at the lowest ebb of human experience.”
As Jonah indicated in a similar situation (Jonah 2:3–7), the psalmist in his sin feels as though he is going down for the third time because of his sin and his resultant guilt before the Lord
be gracious, show favor,” envisions the psalmist begging for the Lord’s gracious response. It is a deep cry from the heart, born of strong emotion. His faith in the Lord directed his feelings to him, for the psalmist realized that even in the depths he was not too far down for the Lord to hear his prayer
The psalmist acknowledges that what humans cannot earn by merit (vv. 1–3), the Lord offers by his grace. By his forgiveness, the Lord proves himself more powerful than sin. His grace, however, should not cause us to think less of him, but it is intended to cause us to respect him. Kraus notes, “To fear Yahweh means to wait for his word of forgiveness, in straining attentiveness to look forward to the moment in which Yahweh grants [forgiveness]. In impressive clearness the psalm unveils the human being’s bearing in view of the free grace of God
the psalmist emphasizes that the Lord’s faithfulness inspires hope in him. This is not a tepid, half-hearted trust, but the psalmist is all in for the Lord as he completely places himself and his need into the Lord’s hands. The repetition in lines b and c suggests a strong sense of expectancy, as he waits for the Lord’s word of forgiveness (cf. v. 4), trusting that the Lord will respond graciously to his supplication. His waiting necessarily involves listening; the psalmist has cried out of the depths to the Lord, and now he is silent before the Lord as he anticipates the divine reply.
Because no fault is too great for the Lord’s forgiveness, there is always hope due to the divine pattern of redemption. As Ross notes, “Every experience of forgiveness is a foreshadowing of the final redemption from sin and everything connected to it.”
the psalmist in Psalm 130 shows how sinners like himself can move from the depths of their guilt to the delights of God’s grace. Attempts to relieve guilt by activity, possessions, achievements, positive thoughts, and denial are as ineffective as taking aspirin to heal a tumor because while they may address the symptoms, they cannot cure the disease. The good news of Psalm 130 is that when sinners cry out to God in the night of their guilt, he is gracious in forgiving them. Their hope is not in their merit before the Lord but in the Lord’s unmerited mercy to them.
