Are you praying for someone who has stopped seeking God? Someone who has drifted so far away from Him that they do not even acknowledge His presence?
Don't give up!
Remember, Saul was not seeking God. Just the opposite. He was killing anyone who believed that God sent His Son, Jesus to bring us salvation. God suddenly revealed Himself to Saul on the road to Emmaus and that encounter so changed Saul that he became the Apostle Paul who penned most of the Bible and lived the rest of his life sharing Christ with others.
Keep praying that God will reveal Himself to those who do not seek Him so that they may be saved.
