What does the Bible say about the joy of a believer?

The joy of a believer is highlighted in Psalm 70:4, where it states, 'Let all those who seek You rejoice and be glad in You.' This joy is rooted in a relationship with God rather than in external circumstances. While worldly joy is dependent on situations going well, biblical joy transcends these conditions, as believers understand that ultimate satisfaction is found only in God. This joy is a gift from God, cultivated through the work of the Holy Spirit, reminding us daily that our happiness lies in the Lord rather than in temporal things.
