What does the Bible say about happiness and blessing?

In Psalm 1, the scripture contrasts the ways of the righteous and the wicked, emphasizing that true happiness and blessing are found in obedience to God's Word. Instead of seeking happiness through worldly means, the blessed man is one who meditates on God's instruction day and night. This meditation allows a believer to bear fruit in their life, akin to a tree planted by streams of water. The psalm emphasizes that happiness is not merely about transient emotions but is deeply rooted in a relationship with God and His guidance.
