Matthew 4:2 And when He had fasted forty days and forty nights, afterward He was hungry.
The devil cannot give you anger, he just exploits it. Be aware of your weakness and ask God to help you. After 40 days fast, Satan knew that Jesus was hungry and tried to tempt Him. If the devil gives you something you desperately need, would you be able to say no? What the devil gives he takes something with the other hand.
