Jesus Christ is our High Priest. In the book of Hebrews, Jesus is shown to be our Great High Priest.
Hebrews 4:14 Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession. [Our profession is Christianity]
We are admonished to seize and retain our profession of faith which is “Christianity.” How do we retain our Christianity?
