Biblical repentance reestablishes credibility with the world and fellowship with the Lord. The seven "what's" of 2 Corinthians 7:11 are seven marks of godly sorrow: (1) Earnestness to do right. (2) Eagerness to clear oneself through apology. (3) Indignation against sin. (4) Fear of God. (5) Intense desire to see right accomplished. (6) Zeal to correct what's wrong. (7) Readiness to see that wrongdoing punished.
For Christians, repentance is an attitude of life. Daily we ask God's Spirit to show us our sin. Then we work on overcoming it. May the ingredient of "godly sorrow" never be missing from our lives!
