Pray it through until you know the doors are shut tightly. Pray it through until you know it is just not right. Pray it through until God says no or until God says yes. Sometimes it is difficult to let it go when you know God says no. Yet when He says no, walk away. The worst place you can be spiritually is somewhere God does not want you to be in your life. Pray it through until God says yes. Thank God for the times in life when your persistence in prayer resulted in God saying yes. What an encouragement!
