We are cleansed by the sacrifice of “the sin offering” which “makes atonement” for us “before the Lord” (Leviticus 14:18). Only those who have received cleansing from their sins through faith in Christ will enjoy the glory of heaven when the Lord returns (Mark 13:27). Psalm 30:8-12 gives an account of faith in the Lord. Realizing the danger of judgment (Psalm 30:9), the Psalmist calls upon the Lord, crying to Him for mercy (Psalm 30:8). God answers the prayer, turning the Psalmist’s “wailing into dancing” and clothing him with joy (Psalm 30:11). The Psalmist sings to the Lord from his heart – “O Lord my God, I will give You thanks for ever” (Psalm 30:12).
