No?
Romans 3:21-26
 21But now a righteousness from God, apart from law, has been made known, to which the Law and the Prophets testify. 22This righteousness from God comes through faith in Jesus Christ to all who believe. There is no difference, 23for all have sinned and fall short of the glory of God, 24and are justified freely by his grace through the redemption that came by Christ Jesus. 25God presented him as a sacrifice of atonement,[
i]
 through faith in his blood. He did this to demonstrate his justice,
because in his forbearance he had left the sins committed beforehand
unpunished— 26he did it to
 demonstrate his justice at the present time, so as to be just and the
one who justifies those who have faith in Jesus.
I am well aware of the fact that I sin. I lust, I curse, I look at pr0n on the interwebz. I also know that my belief in Christ leads to a process of sanctification whereby I feel bad for the things that I do and desire to do them less and less.
I recognize that the only thing which totally and completely justifies me is my belief that the life of Jesus Christ and His Grace is enough of a sacrifice to atone for my sins.
