In this lesson, we discuss the entrance, consequence and knowledge of sin. By one man’s sin all die. All sin and are worthy of death. Man fell from his sinless state to a reprobate standing before God, and he, in his grace, gave man the law to show him his terrible, irreconcilable state if enmity against him. God’s law and the testimony of scripture conclude man under sin in need of a Saviour. Thank God for his law, and his grace through Christ’s cross, to save us from its just condemnation (Rom5:12-21).
