Trust in God's Mercy: From Sorrow to Rejoicing

Psalms 13:5 presents David's watershed moment: "But I have trusted in Thy mercy." Joseph Exell's Victorian commentary illuminates what this trust demands and delivers.

Mercy (eleos) differs fundamentally from goodness—it presupposes guilt. Without human fall, redemption would be meaningless; without redemption's plan, we could never comprehend Divine mercy. God addresses man's two interlocked evils: sin and death, cause and effect. Against sin, Elohim provides Scripture's light; against death, the regenerative principle infused at baptism.

True trust requires first knowing what we fear. Self-satisfied men rest in mistaken confidence, confusing presumption with faith. Trusting Adonai means renouncing self-reliance entirely—not merely seeking deliverance from punishment, but deliverance from sin itself.

David's testimony bridges despair and anticipation: "My heart shall rejoice in Thy salvation." He mourns God's delays yet anchors his soul in mercy. His is experiential knowledge, not dry doctrine. Only those who have been "heart-achers" comprehend heart-rejoicing. The Psalmist declares the blessed paradox: "Blessed are they that mourn, for they shall be comforted."

This shelter—this anchor—cannot shipwreck. The peace of God surpasses worldly measure. David's progression from lament to confidence models discipleship's essential test: whether we trust Yahweh's mercy through Jesus Christ with the same experimental certainty.
