We know our true spiritual state by how troubled we become over our slightest sin against our Lord.

Some Christians only grieve over what they consider the “big sins”— adultery, drug abuse, drinking, cursing. But the truly spiritual
person knows that no sin is small in God's sight and so he grieves every time he gossips, tells a dirty joke or has a lingering evil thought. He knows these things spring from his heart, the very center of his being.

You can disobey God in such “small things,” excusing yourself and forgetting all about them. But if you do, you will never mature in Christ. Your righteousness is measured by your unwillingness to accept anything that grieves your blessed Savior.

This is Godly sorrow.

“Now I rejoice, not that ye were made sorry, but that ye sorrowed to repentance: for ye were made sorry after a godly manner.” 2 Corinthians 7:9
