Now that you have accepted the gift of salvation now what? In all honesty, LIFE begins a new. The past is the past no matter what you have done and the journey is ahead of you. What journey are you talking about? Your WALK with Christ!
Now is the time for you to search out perhaps a Church that follows Biblically principles and find a Bible that you like because you will be spending a lot of time in it. This is hard but not as hard as it will be to follow Christ! Learn and read all you can! Ask questions because there are many that you will have and seek fellow believers! These are just stepping-stones in your journey!
