I would like everyone to read Matthew 4: 1-11


Then Jesus was led up by the Spirit into the wilderness to be tempted by the devil. And when He had fasted forty days and forty nights, afterward He was hungry. Now when the tempter came to Him, he said, “If You are the Son of God, command that these stones become bread.”
But He answered and said, “It is written, ‘Man shall not live by bread alone, but by every word that proceeds from the mouth of God.’”
Then the devil took Him up into the holy city, set Him on the pinnacle of the temple, and said to Him, “If You are the Son of God, throw Yourself down. For it is written:
‘ He shall give His angels charge over you,’ and,
‘ In their hands they shall bear you up,
Lest you dash your foot against a stone.’

Jesus said to him, “It is written again, ‘You shall not tempt the LORD your God.’
Again, the devil took Him up on an exceedingly high mountain, and showed Him all the kingdoms of the world and their glory. And he said to Him, “All these things I will give You if You will fall down and worship me.”
Then Jesus said to him, “Away with you, Satan! For it is written, ‘You shall worship the LORD your God, and Him only you shall serve.’”
Then the devil left Him, and behold, angels came and ministered to Him.

Jesus fought Satan with scripture. This passage is a clear statement of how powerful scripture is.
If it can fight off Satan it is powerful, if it is GOD'S HOLY BOOK then it is powerful.
If it is something that GOD thinks is holy, then it is powerful.
If GOD says it is holy, then it is powerful.
The bible is a powerful thing. God has given us this powerful thing and we can use it to our advantage over Satan.
