For there is one God, and one mediator also between God and men, the man Christ Jesus, who gave Himself as a ransom for all, the testimony given at the proper time.
The only mediator between us and God the Father is Jesus Christ. Jesus paid the ultimate price so that we could have a restored relationship with our Father in Heaven. It is our sin that separates us from God and every person born upon the earth is born into sin. But Jesus gave His life that was without sin to be the ultimate sacrifice. Anyone who places their faith and trust in Jesus Christ is able to draw near to the Father with full confidence knowing that their sin no longer remains.
There are some who believe you need to go through a priest to get to God. But this is not true and it is not based upon the truth of God’s word. Under the Old Covenant the people went to the priests who were from the tribe of Levi and the High Priest was the only one who could enter the Holy of Holies but once a year on the day of atonement. But under the New Covenant Jesus has become our great and compassionate faithful High Priest. He sits at the right hand of the Father living to intercede for us. None of our sin remains and every day and every moment we have in Him is brand new. We are new creations and our identity is found alone in who Jesus is.
