The old covenant, based on the principle ‘Keep My commandments, then you will receive My blessing,’ which God has made with humans, has been replaced by God through the New Covenant.
“The former regulation is set aside because it was weak and useless (for the law made nothing perfect), and a better hope is introduced, by which we draw near to God.” (Hebrews 7:18-19; NIV)
If the Old Covenant had been sufficient, it would not have been necessary to replace it with something better (Jeremiah 31:31-32).
“But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.” (Galatians 3:11; KJV)
So believe in Jesus as your Savior, so that you are reconciled with God forever.
Jesus has taken your punishments, so that God will never have to punish you again.
