"Therefore, brethren, having boldness to enter the Holiest by the Blood of Jesus,...let us draw near with a true heart in full assurance of faith...." (Hebrews 10:19 & 22a)
Every senior at my seminary had to preach a "senior sermon" in one of the seminary chapel services. I used the above text for the sermon and the following litany as a part of that service.
