Proverbs of a 36 yr old man
Jesus paid in full the debt of sin we owe to God. We need no further sacrifice for sin. The blood of bulls and goats was not sufficient enough to cover the sins of the people, the guilt remained afterward. But on the Cross the entire work of redemption was completed forever, saving us from sin and eternal punishment. The blood of Christ also cleanses our consciences from useless acts so we can serve the Living God, no strings attached. Meaning we do not have to rely on worthless works of the flesh to please God. We are new creations in Christ and God is pleased when we live for him the way Jesus lived for us. Sin required a sacrifice of death, Jesus provided that. But now righteousness requires a sacrifice of life, so go and serve the Living God with a pure conscience. Knowing you have a new heart and new spirit within you. You are one of God's most amazing creations, a living sacrifice. Study 2 Cor. 5:17
