Deuteronomy 3:22 Ye shall not fear them: for the LORD your God he shall fight for you.
As they prepare to enter the Promised Land Moses tells them not to be afraid. God has shown them how He destroyed two kings. He promises that He will do the same with the rest.
God has saved us. He has given us new life. He has brought us to where we are today. Yes, things are facing us and they may be scary but remember that it is the Lord that fights for you! The hardest thing that we have to do is trust. We believe God but maybe not in the moment and in the face of our trial.
So take a minute and think of how good God has been to you! Realize that He has always cared for you and remember that He will do so again!
