How do we know that Jesus is our access to the Father?

In Ephesians 2:18, the Apostle Paul emphasizes that it is through Jesus Christ that we have access to the Father. This access is only possible because of the redemptive work of Jesus, who by His death and resurrection opened the way for us to come before God. Hebrews 10:19-22 reiterates this by stating that we can enter the holiest place by the blood of Jesus, illustrating that no one comes to the Father except through Him. This is crucial in understanding the exclusivity of Christ as our mediator.
