Peter quotes the timeless counsel in Psalm 34.
Seek means searching diligently, not giving up after a cursory glance.
Pursue means with tireless effort, not giving up until it is attained.
Seek peace with God.
Deal with the sins which separate you.
Seek peace with others.
Seek it. Look for the best, for common ground.
Pursue it. Forgive. Reconcile. Give the benefit of the doubt.
Seek peace within.
A clear conscience before God.
A calm confidence in God.
The benefits? Peter explains in verse 10. You love life. You see good days.
Counsel worth heeding.
