They said, Turn ye again now every one from his evil way, and from the evil of your doings, and dwell in the land that the LORD hath given unto you and to your fathers for ever and ever:
You can't go back but you can start where you are.
Gods promises
1- I won't harm you.
2- When you need me call me.
3- When you seek me with your whole heart, you will find me.
