23For all have sinned, and come short of the glory of God;
24Being justified freely by his grace through the redemption that is in Christ Jesus:
We have all sinned, and we have all done things we are ashamed of, but Our Lord and Saviour Jesus Christ forgives us. He loves us, and He is here for us to cleanse us of our sins, and make us pure again. Don't despair. Read the Bible. Pray. Talk with someone you know and trust(Maybe your pastor, or a church friend), and have faith in Jesus Christ.
