Before Jesus began his ministry, he goes to the desert to fast for 40 days. This was an amazing feat.
12 – And immediately the Spirit driveth him into the wilderness.
13 – And he was there in the wilderness forty days, tempted of Satan; and was with the wild beasts; and the angels ministered unto him.
Matthew Chapter 4 and Luke Chapter 4
Both these chapters from the Gospels explain in detail how Jesus was tempted in the desert.
First, the devil tells him to turn stones into bread. After all, Jesus was very hungry trying to fast in the desert. But Jesus responds that it is written that man lives not by bread alone but by every word that proceeds from the mouth of God.
The devil then took Jesus to the top of the pinnacle of The Temple. The devil tries to get Jesus to throw himself down. After all, if Jesus was truly the One, God wouldn’t let him die. He would send angels to keep him from falling. But Jesus responds that it is written that one should not tempt God by asking him to perform miracles unnecessarily.
Finally, the devil tries to get Jesus to worship him. But Jesus responds that again it is written that you should only worship the LORD your God.
18 – The Spirit of the LORD is upon me…
After fasting for 40 days and being tempted of the devil and resisting each time, Jesus was full of the Spirit. Jesus quoted this Scripture and said it was about him. He was ready to begin his ministry. The Gospel of Matthew describes angels ministering unto Jesus when he finished his trials in the desert (Matthew 4:11). But when Jesus reads these words that the Spirit of the LORD is upon him, he officially begins his ministry.
We should all strive to have the Spirit of the LORD upon us like Jesus when he is quoting this Jewish Scripture. We should also remember his 3 responses to the devil when he is tempted in the desert. Man does not live on bread alone, you should not tempt God, and you should only worship God. Man lives by every word that proceeds from the mouth of God.
