Matthew 4:4 - Jesus answered, “It is written ‘Man does not live on bread alone, but on every Word that comes from the mouth of God.”
Jesus was the same as we are now. He was 100% God and 100% man. He was different, of course, in the sense that He was God first, and then He came to earth in the flesh. Jesus was the firstborn.
We started in the flesh and then were reborn into God. But the point still remains that when Jesus came to earth He received the same sinful nature that we have. He had to; if not, He would not have been able to go through the same temptation as we did.
Jesus did, however, come in the flesh and He did go through everything that we go through. He faced every temptation and every sin, but He stood His ground. Jesus never sinned.
So when we are facing temptation and sin we can first know that Christ went through the exact same thing, and then we can look to Him to find out how to say no.
Notice during Jesus time in the desert when satan was tempting Him how He handled it. Satan saw Jesus physical desires and wants and appealed to His flesh. He offered bread to a starving man; he offered immortality to a God who had taken a mortal body; and he offered kingdom authority to one who had stepped out of His kingdom.
Just as satan attacks you and me he also attacked Jesus; with the desires of the flesh. Jesus however turned it around and brought in the spiritual. When our flesh is weak, our spirit is made strong.
If you are facing temptation the best thing to do is look to the spiritual. Just as in this verse, if you are tempted with food, look to the Word to get spiritual nourishment. Through Christ and with God’s Spirit inside of us we have the ability to face temptation and stand firm.
