The new covenant
God has established a new covenant with men through Jesus Christ. According to God's law, a covenant can only be made when there is shedding of blood, and the blood of Jesus was shed to establish the new covenant. "Likewise He also took the cup after supper, saying, "This cup is the new covenant in My blood, which is shed for you." (Luke 22:20, NKJV).
The new covenant replaces the old one that God had established with the Israelites through Moses.
This old covenant is callled the "ministry of death" (2 Corinthians 3:7) as those who did not obey the law were punished even by death. The new covenant is called the "ministry of righteousness" (2 Corinthians 3:9) as Jesus came to save men and not to condemn them. "For God did not send His Son into the world to condemn the world, but that the world through Him might be saved." (John 3:17, NKJV).
