Look at the progression that is outlined in this verse. Look at how we can get sucked into a life of ungodliness that robs us from the blessed life.
1. The blessed or happy man does not WALK in the counsel of the wicked. Walk is a term that suggests passing by, casually “checking it out”.
2. The blessed or happy man does not STAND in the way of sinners. The Hebrew word for stand has the idea of actually mixing in, standing among, sinners. Can you see the progression here? The casual passerby slows down and now takes his stand with the sinner.
3. The blessed or happy man also does not SIT in the seat of mockers. This suggests something more permanent, an abiding, a settling down. You’re all in. It’s bad news. It pulls you in and the next thing you know, you’re in bed with the enemy.
The Psalmist is telling us that we find true blessing and true happiness when we don’t walk, stand, or sit with the ungodly.
Quoting a well-known proverb, the Apostle Paul warns us…
Do not be misled: "Bad company corrupts good character." - 1 Corinthians 15:33
Entertaining ungodliness and/or hanging out with the wrong people results in anything but blessing and happiness.
