A chasm exists between men and God. [God is represented as “Light – pure and holy” Mankind in his sinful state is represented as “Darkness”.  The two cannot be together and remain in the original state]. That distance between Creator [God] and creation [man] needs to be bridged by one who is mutually representative. People are fallen humans in need of a mediator between ourselves and God. People need him [mediator] to represent us judicially. People are all corrupted with the guilt of Adam and are born with sin-enslaved souls. Moral offense separates mankind from God and requires reconciliation on the grounds of atonement by the Messiah. Jesus Christ is that Mediator between God and man. [Heidelberg Catechism Q&As 15-19  – link to CRCA website)

“For there is one God, and one mediator also between God and men, the man Christ Jesus” (1 Timothy 2: 5);  “For this reason He is the mediator of a new covenant, so that, since a death has taken place for the redemption of the transgressions that were committed under the first covenant, those who have been called may receive the promise of the eternal inheritance.”(Hebrews 9: 15)
