Deuteronomy 31: 6 – 8
6 Be strong and of good courage, do not fear nor be afraid of them; for the LORD your God, He is the One who goes with you. He will not leave you nor forsake you.”
7 Then Moses called Joshua and said to him in the sight of all Israel, “Be strong and of good courage, for you must go with this people to the land which the LORD has sworn to their fathers to give them, and you shall cause them to inherit it. 8 And the LORD, He is the One who goes before you. He will be with you, He will not leave you nor forsake you; do not fear nor be dismayed.”

I love that promise - He will NOT leave you nor forsake you; do not fear! Even when we turn our backs on God He is still right there waiting for us to come on back home. One thing we need to remember though is that He will not tarry forever - time is short!
