Jesus Christ was the final Sacrifice for the sins of the people (Hebrews 10:10). In the Old Testament period, the priests and people would gather to offer sacrifices for their sins year after year. However, these annual sacrifices never took away their sins, but only provided temporary relief. These sacrifices were only a shadow of Jesus Christ’s ultimate sacrifice.
Still more, God desired the people’s wholehearted love, obedience and a right heart for Him as God and not just religious rituals and sacrifices (Hebrews 10:22). In fact, one of the central teachings of the Old Testament and the New Testament are not gifts and sacrifices, but wholehearted and genuine love, faith, and obedience for God (1 Samuel 15:22-23; Psalm 40:6-8; Psalm 51:16-19; Isaiah 1:11-15; Jeremiah 7:21-23; Hosea 6:6; Amos 5:21-24; Micah 6:6-8; Matthew 9:13; and Matthew 22:34-40). Sacrifice and rituals are not unimportant. However, genuine love, faith, devotion, and obedience to God are far better in God’s eyes than following empty, half-hearted rituals and rules (Hebrews 10:5-7).
Moreover, the people needed a permanent and greater sacrifice for forgiveness of their sins from within their hearts. Jesus Christ offers to all people by faith that permanent and final forgiveness of sins. God sent Jesus Christ to offer His sinless body on the Cross as our final sacrifice for sin. Moreover, Jesus Christ’s death on the Cross did away with the sacrificial system contained in the ceremonial Old Testament law (Jeremiah 31:31-34; Hebrews 10:16-18). However, Jesus Christ’s death did not eliminate God’s moral law (e.g., the Ten Commandments at Exodus 20:3-17; Deuteronomy 5:7-21). Thus, God's new way to please Him is by faith in His Son, Jesus Christ. When we genuinely and wholeheartedly confess our sins, Jesus permanently and forever removes our sins and cleans us from the inside of evil, sin, and wickedness (see also 1 John 1:9). Best of all, God remembers our sins no more.
Moreover, Jesus Christ sends His Holy Spirit to live within our hearts to help us obey God’s moral law and walk with Him in obedience and love (John 14 – 16). God wants everyone to wholeheartedly love Him and to obey His will. When we truly trust in Jesus Christ to forgive our sins, God’s Holy Spirit to help us walk with God and grow holy and righteous. If we stumble, Jesus Christ encourages us to confess our sins to God and God promises to continually forgive us (Matthew 6:9-13; Luke 11:2-4).
God through Jesus Christ offers everyone the free gift of eternal life and salvation so we can now concentrate on loving others and doing good work (Galatians 5:13; Ephesians 2:8-10). We are saved not by following the law or good deeds but by God’s grace. However, we are saved to do good works for God’s glory (Ephesians 2:8-10).
