Quit looking behind you, you can’t do anything about it!
Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God. Hebrews 12:2
Get your eyes fixed on Jesus and you will not have to worry what happened in your past! As a matter of fact, if your eyes are truly fixed on Him, you will not have to worry about your future either!
