All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work. 2Timothy 3: 16-17
The Bible is the means God has given us for training and equipping us to do His work here on earth. Within its pages is absolute truth in a world that is blurred into grey. That is why the enemy spends so much effort to try and marginalize it. Because if he can succeed in confusing people into thinking the Bible is not absolute truth, then his lies work much more effectively. Because while God is truth, the enemy is the opposite:
You belong to your father, the devil, and you want to carry out your father's desire. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies. John 8:44
Lying is the native language of the enemy. There is NO truth in him. None. Conversely, there is nothing deceptive in God. They are opposites. Now that we have established the absoluteness of truth in God and the absoluteness of deception in Satan; we can better understand how the enemy attacks us. The enemy seeks a conversation with us, where he can tell his lies for our consideration. That is it. We give too much power to the devil sometimes. The devil cannot make you do anything because if he could, he would kill us all. He can't. All he can do is present us with an argument; something for us to consider. It will always be in opposition to the truth we know in God. Just as he whispered to Eve and Achan and Ananias and Sapphira he will whisper into our lives as well.
"You have no hope for a future, just give up."
"It's only a little money; they won't even notice it is missing."
"Your wife doesn't give you what you need, God understands."
No hope for a future? Try Jeremiah 29:11. Only a little money? Try Exodus 20:15. Confused about adultery? Try reading Matthew chapter five. For ANY lie the enemy whispers into your life God has the promise or command in His Word to counteract that lie. Remember, what the enemy represents is always a lie. It is not possible for him to tell the truth. What God represents is always the truth; it is not possible for Him to lie. Which are you going to believe? This is the essence of spiritual warfare. The enemy to your soul has lied to you and is presenting to you something for you to consider. To Eve, he had her considering the possibilities of being like God. For Achan, the enemy had him considering what God had said was untouchable; the taboo. For Ananias and Sapphira, the enemy used greed to distort the truth in their lives.
