“No matter how righteous you are, or how moral you are, or how religious you are, or whether God has produced all that in you or you have produced that in yourself, do not trust in anything that is in you, or that you do, as the basis of your justification before God. That is not how you are accepted. That is not how you come into God’s eternal favor. That is not how you will be justified now or in the last day. Trust in Christ—his blood and righteousness—as the sole basis of your justification.”

~John Piper. From the message given at T4G: Did Jesus Preach Paul’s Gospel?
