No matter what happened in the past, leave it alone. It will trip you up for your future. Work through the left over emotions with God while you keep moving forward in His way.
Holy will keep you going when you let Jesus have it. He will keep you from stumbling when you stay focused on Him instead of becoming distracted by life.
Forget the former things; do not dwell on the past. See, I am doing a new thing! Now it springs up; do you not perceive it? I am making a way in the wilderness and streams in the wasteland. Isaiah 43:18
