There will be times when God will stop His hand from bringing judgment, punishment or destruction on individuals all because of one person standing in the gap interceding and praying, and crying out for the lives of others to be saved. God is not moved by lots of people praying at one time, but by the sincere heart of one person who prays at all times.
Psalms 106:23 says “God wanted to destroy those people, but Moses, the leader He chose, stood in the way. God was very angry, but Moses begged him to stop, so God did not destroy the people.”
Be blessed, be encouraged, and have a great day.
