Ephesians 6:10-11 - "Finally, be strong in the Lord, and in the strength of His might. Put on the full armor of God, that you may be able to stand firm against the schemes of the devil."
James 4:7-8 - "Submit therefore to God. Resist the devil and he will flee from you. Draw near to God and He will draw near to you. Cleanse your hands, you sinners; and purify your hears, you double minded."
Jesus Christ is our truth, righteousness, and faith. He is the embodiment of this armor. Without him it is impossible to wear the armor. The new treatment commands us to resist the devil and out on the armor of God.
The devil is a formidable foe, coming as a roaring lion, seeking whom he may destroy. His first appearance in scripture is in Genesis. Here he questions what God has said and contradicts the consequences of disobedience. "Has God said you should not eat the fruit of the tree of the knowledge of good and evil? You shall not surely die. You will be like God if you eat this fruit." He comes to us and desires that we question God's Word. The devil was created by God as a brilliant and beautiful angel. Because of his pride, he was cast out of heaven and now works with spiritual host of wickedness in the heavenly places. He will attack, but the Word of God promises if we have on the armor of God, we will be able to stand against him. Therefore, we should focus our attention on the armor, The rest is up to God, who promised in Isaiah 56:19, "When the enemy comes in like a flood, the Spirit of the Lord will Lift up a standard again him."
