What does Psalm 90 teach about the relationship between sin and God's anger?

Moses, in Psalm 90, confesses that we are consumed by God's anger because of sin. This acknowledgment of sinfulness is vital to understanding our need for redemption. The psalmist expresses that God sets our iniquities before Him, highlighting God's omniscience and holiness, which cannot tolerate sin. Such a perspective aligns with Reformed theology, which emphasizes the seriousness of sin and the subsequent need for Christ's atoning sacrifice. Recognizing God's anger allows believers to appreciate the depth of His mercy, as it is through understanding our sin that we can grasp the grace offered through the gospel.
