8 If we say that we have no sin, we are deceiving ourselves and the truth is not in us. 9 If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness. 10 If we say that we have not sinned, we make Him a liar and His word is not in us. 1 John 1:8-10 (NASB)
Sacred Scripture’s diagnosis of sin is as a universal deformity of human nature found at every point in every person (1 Kings 8:46; Romans 3:9-23; 7:18; 1 John 1:8-10 see above). Both the Old Testament and the New Testament describe sin as rebellion against God’s rule, missing the mark God set for us to aim at, transgressing God’s law, offending God’s purity by defiling oneself, and incurring guilt before God the Judge. The moral deformity is dynamic: sin is an energy of irrational, negative, and rebellious reaction to God. It is a spirit of fighting God in order to play god. The root of sin is pride and enmity against God, the spirit seen in Adam’s first transgression, and sinful acts always have behind them thoughts and desires that one way or another express the willful opposition of the fallen heart to God’s claims on our lives.
