I found that, though this book of lyrics are often attributed to David, he actually wrote about seventy-three (about half) of the songs. The Palms were written over a period of one thousand years from Moses to Ezra (Believer's Bible Commentary - Kindle).
1 Blessed are those whose ways are blameless,
who walk according to the law of the Lord.
2 Blessed are those who keep his statutes
and seek him with all their hearts.
These two verses say lot to the reader. In a nut shell, to me it convicts me and tells me to walk with God instead of the worldly. To "seek him with all [our] hearts". Then, we shall be blessed with His love.
God bless you,
