"Therefore he had to become like his brothers and sisters in every respect, so that he might be a merciful and faithful high priest in the service of God, to make a sacrifice of atonement for the sins of the people."    - Hebrews 2

This is a hard one to grasp, unless we take it at face value.

Jesus became just like us.

Just like us.

He would get cold, hungry, and angry. Presumably, He had all the same urges.

And it's essential that we understand that He was able to overcome every temptation. When He was presented at the temple as a boy, two people full of the Holy Spirit approached Mary and Joseph and affirmed that their son was the Promised One. How did they know this? They had great faith, and they stayed in the Temple all day long, praying.

Jesus had those disciplined practices even more. 

It is possible to overcome temptation. You have to pray, fast, get into God's, and fellowship with other believers. But most importantly, you have to want to be holy.

If He did not respond to Nature in just the same way as us, then He could not be our redeemer. He had to be just like us. 

And this gives us hope that we have a Redeemer that matters, because we matter to Him. And we also know that we are able to master temptation, for He showed us how.

And the main ingredient is desire to be sinless.
