Are you saying you are perfect? If you are, then you're the first perfect person I've ever met.
Are you saying you've never broken the Law of God? Have you ever lied, cheated, or stolen? If you have, then you are a sinner whether you think so or not. The laws of God have punishments (a law without a punishment is only a slogan). As a sinner, you are separated from God (Isaiah 59:2). However, God loves you enough not to want you to be separated from Him. He sent Jesus (1 John ) to pay for your sins on the cross. So, the only way to have your sins forgiven is to put your trust in Jesus, and the sacrifice He made.
The Bible says that everyone has sinned (Rom. ). That means you, too.
