Sin within a person’s life messes with man’s conscience. It begins by attacking man’s knowledge of God with the end goal of causing a complete rejection of God. Sinful man turns to many different devices in hopes of taking care of his sin-tainted conscience. He may seek to pacify his conscience by doing religious works. He also may try to forget that his conscience has been corrupted by a further turning toward the pleasures of sin. In both cases, he is left with a conscience in need of purging. Where can man turn to find the purging he so strongly desires? According to the Bible, only the blood of Jesus Christ can purge a man’s conscience from dead works to serve the living God (Hebrews 9:14).
God demands righteousness, and when man fails to meet His standards, He calls for the shedding of blood for the remission of sins (Hebrews 9:22). Throughout the Old Testament, sacrifices majored on the blood of animals, but these animal sacrifices could never take away sins (Hebrews 10:4). God, in mercy, sent His Son to give “himself for us an offering and a sacrifice to God for a sweetsmelling savour” (Ephesians 5:2). Unlike the Old Testament sacrifices, the Lord Jesus was a single onetime sacrifice that offered forgiveness of sin for all and to all. In shedding His blood, the Lord Jesus Christ became man’s sacrifice, and man need look no further than the shed blood of Christ for the means by which God is satisfied.
