What does Psalm 32:7 mean?

The Lord adds protection to forgiveness. In this context, this refers to God keeping His people from the distress of conviction. Unconfessed sin creates discomfort in the spirit of a believer (Revelation 3:19; Hebrews 12:6; Psalm 32:1–4). David tried to hide his sins from the Lord; doing so led to great distress. However, when he confessed his sins and received forgiveness (1 John 1:8–10), he found a secure relationship with God (Psalm 51:1).

Using military imagery, David regarded himself as surrounded by the enemy but delivered by the Lord. The deliverance brought shouts of deliverance. Paul perceived the Christian life as under attack from a sinister enemy, the Devil. However, he recognized that victory comes from employing spiritual weapons and prayer. Paul assured the Christians at Rome that believers are on the winning team! He exulted: "We are more than conquerors through him who loved us" (Romans 8:37).
