So He said to them again, “Truly, truly, I tell you, I am the gate for the sheep. — John 10:7

Jesus says plainly: I am the door. There's only one way into the sheepfold, and it's through Him. When He died, the veil of the temple was torn in two, opening a new and living way through His flesh. Christ also suffered once for sins, the just for the unjust, that He might bring us to God. Through Him we both have access by one Spirit to the Father.
