Psalm 1 begins with the following list of actions that cause a man to be blessed:
Psalm 1:1-2
Blessed is the man who does not walk in the counsel of the wicked or stand in the way of sinners or sit in the seat of mockers. But his delight is in the law of the LORD, and on His law he meditates day and night.
These are instructions on how to “position ourselves for blessings,” as some have said. There are three things a blessed man does not do: if you want to be blessed, then stop taking advice from the wrong people, don’t live your life the same way that sinners live theirs, and don’t mock God with your attitude. Also, there are two things a blessed man does do: delight in the law of God and think about it all the time.
