Ephesians 6:10-12 says, "Finally, be strong in the Lord and in his mighty power. Put on the full armor of God so that you can take your stand against the devil's schemes. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realm."
We have to constantly use Jesus as the perfect example of how he resisted temptation through spiritual warfare. Each temptation was combatted with the word of God. In Matthew 4:3 "And when the tempter [devil] came to him, he said, if thou be the Son of God, command that these stones be made bread." Jesus answered and said, "It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God." The word of God is the most powerful weapon against the temptations of the devil.
Remember, you are not meant for weakness. You are meant for strength; a strength that comes not from you, but to you, from Christ. The armor you wear is God's armor and it's yours for the wearing. Now, Go Win!
