And for this cause He [Jesus] is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
Jesus, the Son of God, our Savior is our mediator. Not Mary His mother, or any early priest or prelate. Only Jesus can bridge the gap between you and God...a gap that your sin has caused. A gap that will remain constant and eternal unless you put your faith in Him. Often, we read about 'mediation' in the sporting world when the players union is threatening a strike. But spiritual, we have sinned against God and have alienated Him from us. We've created a rift by not following our contract.
We can rely on our own defense whatever it may be. We can rely on our church membership or on a religious family member and a philanthropic affiliation. But the Bible says that Jesus, not those things previously mentioned, is the mediator.
And He mediates by means of death. His death. His blood. His sacrifice. That is the way of redemption. Not through His healing, or His teaching or His moral life. Only through His death are we redeemed and forgiven.
John Gill wrote “What he bore were 'sins'; all kind of sin, every act of sin, and all that belongs to it; its filth, guilt, and punishment, even the iniquity of all his people; which must be a prodigious weight, and than which nothing could be more nauseous: his bearing them supposes they were upon him, though not in him, imputed, though not inherent; that he did not sink under them; that he made an entire satisfaction for them, and bore them wholly away, both from the persons of his people, and from the sight of justice.”
Trust in Jesus, dear friend. He is the only way you can be reconciled to God.
