Rachel explains the first half of Hebrews 4 v15 and explains how Jesus is The Great High Priest for those who trust Him. He acts as a link between us and God, who speaks on our behalf and perfects our prayers.

Hebrews 4:15

15 For we do not have a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tempted as we are, yet without sin.

(ESV)
