You are doing exactly what you need to do in preparation to trust Christ Jesus as your Lord and Savior, and that is repenting of past sins. Remember, once your saved, you must not go back into those sins that you're walking away from. Once in a while we all slip back and fall. BUT Jesus picks us up, cleans us up, and forgive us.
Tomorrow, you will be a new Nai, to the praise of our Heavenly Father, and His Son Jesus, and the Holy Spirit.
I praise Nick for putting me in your path so that Jesus could extend His arms out to you and say "COME TO ME I'LL MAKE YOU A NEW CREATION".
I Love You Nai,
