Speak the word of God against every temptation 
that comes against you and you will not sin, 
but get victory in Jesus Christ. 
Jesus spoke the word against temptation from satan.

"Then saith Jesus unto him, Get thee hence, 
Satan: for it is written, 
Thou shalt worship the Lord thy God, 
and him only shalt thou serve.
Then the devil leaveth him, and, behold, 
angels came and ministered unto him."
Matthew 4:10-11 (King James Version)

"Then Jesus said to him, “Go away, Satan! 
For it is written: 
‘You are to worship the Lord your God and serve only him.’” 
Then the devil left him, 
and angels came and began ministering to his needs."
Matthew 4:10-11 (New English Translation)

If/when you sin, then you let a demon get into you, 
cast that demon out in the name of Jesus Christ. 
Every Christian that trust the word of God (the Bible) 
and walks with God, 
have power over ALL evil and unclean spirits.

"Then he called his twelve disciples together, 
and gave them power and authority over all devils, 
and to cure diseases."

power and authority over all demons and to cure diseases"
