Prayer of supplication

How can I cleanse all my evil? How are you going to get close to me? If it is not by your blood that cleanses my being? But I do what I do not want to do. That's why I'm asking.
Help me to get out of the hole in which I got myself, help me escape my infidelity, help me to be always, right in the center of your will, helps to live nice to you.
An offering for you, I want to be, holy and pleasant that you can see me, because you won, I won, because I was born of you and I want to look like Jesus.
