When God tells us not to go back to our old ways, we need to forget the past and leave it behind us. Focus on the present and ask the Lord daily what He needs you to do. No matter what took place in your past, you have a hope and a future in Jesus Christ. Renew your mind daily with the Word of God and seek Him first.

For I was told by the word of the Lord, You shall not eat bread or drink water there or return by the way that you came. 1 Kings 13:17 (AMPC)
