Hebrews 4:15 For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.
Jesus Christ is the High Priest of every believer. He left His throne in Heaven to come to this Earth to pay the price for our sin. He is the One Who entered into the Holy of Holies with His own blood to propitiate the wrath of God.
Like the high priests of ancient Israel, Jesus Christ was among mankind when He ministered. He felt pain, hunger, thirst. He knew temptation, even by Satan himself! Yet, He lived a perfect life without sin. That is what made Him the perfect, spotless Lamb of God, Who could take away the sin of the world (John 1:29).
