But eventually, as sins pile up, we become more and more numb. Your conscience might become desensitized to sin. It may be painful, but you can deal with it. Stop ignoring your sins. Then, just like Novocaine wearing off, you will feel more sensitive to sins which even shortly before, did not seem like such a big deal.

Living by the flesh when you belong to Jesus can be just as unpleasant. Lord, I don't want my conscience to become insensitive to sin. Keep my heart open to You. The easier it is to sin, the harder it is to hear God.
