God established a covenant with His people, Israel, by which He invited them into fellowship with Him. Nevertheless, Israel could not keep their end of the covenant. If there was going to be perfect harmony with God, God Himself would have to reconcile His people unconditionally. So God, through His Son, provided a New Covenant. This New Covenant is efficacious because it secures several eternal blessings that God Himself puts into effect for those to whom the covenant is extended.
