Psalm 1 separates mankind into two groups: those whose happiness is founded in the eternal and those whose happiness is merely temporal. There is a downward progression of walking, standing and sitting with the enemies of God that the happy man avoids, followed by seven things of life said about this happy man. The ungodly, by contrast, are like chaff: easily blown away and doomed. True blessed happiness is found by delighting and staying in God's Word.
