 You have to repent or make a change of mind leading to a change of action to forsake the sins that put Jesus on the cross. And you must be baptized or immersed in water for the forgiveness of your sins, being united with Christ in baptism, Acts 2 and 38. And then go on to live a faithful life, walking in the clearly defined paths that God has left us in his word. If we can help you in any way, please let us know.
