What does the Bible say about joy and gladness?

In Psalm 51:8-13, David seeks restoration of the joy of salvation after recognizing the weight of his sin. This highlights the biblical principle that joy is not merely an emotional state but a profound spiritual experience rooted in knowing God and His grace. In scripture, joy is often linked with the presence of the Lord, as believers experience profound happiness when in right relationship with God through faith in Christ. Joy is part of the fruit of the Spirit and is a response to understanding the depths of His love and redemption.
