If a high priest sinned, he was required to bring a sin offering to the temple (Leviticus 4:3-12). He could relate to the people because he was subject to the same frailties they were, even though he was called by God. Jesus was also called by God to be our high priest, as Psalm 110:4 shows. Even though He Himself was without sin (2 Corinthians 5:21), He struggled and suffered and wept and prayed, which is why He can relate to us (Hebrews 4:15).
Luke 22:39-46 “Then Jesus went out and made his way, as he customarily did, to the Mount of Olives, and the disciples followed him. When he came to the place, he said to them, ‘Pray that you will not fall into temptation.’ He went away from them about a stone’s throw, knelt down, and prayed, ‘Father, if you are willing, take this cup away from me. Yet not my will but yours be done.’ Then an angel from heaven appeared to him and strengthened him. And in his anguish he prayed more earnestly, and his sweat was like drops of blood falling to the ground. When he got up from prayer, he came to the disciples and found them sleeping, exhausted from grief. So he said to them, ‘Why are you sleeping? Get up and pray that you will not fall into temptation!’”
In fact, He was heard because of His devotion! But we note that this hearing didn’t mean that He escaped the cross. The whole purpose of the incarnation was for the cross. Jesus took on humanity and suffered as a result of His obedience.
Philippians 2:6-9 “who, though he existed in the form of God, did not regard equality with God as something to be grasped, but emptied himself by taking on the form of a slave, by looking like other men, and by sharing in human nature. He humbled himself, by becoming obedient to the point of death —even death on a cross! As a result God highly exalted him and gave him the name, that is above every name,“
In fact, God incarnate, the second person of the divine Godhead, learned perfect obedience through the cross, and He “became the source of eternal salvation to all who obey him.” If that doesn’t blow your mind, nothing will!
This can be difficult to understand, but it’s important for us to get. It’s the “solid food” that we should be chewing on as adults in the faith. This “solid food” teaches us the magnificent truth about the incarnation and the price that was paid for our salvation. It also teaches us that suffering has role to play in our lives, and we become better and more mature, or “perfected” as a result of it.
