This is from a Bible study I wrote years ago and it seems to fit with our topic this month.

DECEIT–Satan always seeks to deceive us, and often his falsehoods sound good. “When he lies he speaks his native language for he is a liar and the father of lies.” John 8:44
DOUBT–The devil questions God’s Word and His goodness. “Now the serpent was more crafty than any of the wild animals the Lord God had made. He said to the woman, “Did God really say, ‘You must not eat from any tree in the garden’?” Genesis 3:1
DIVERSION–Satan draws our attention the wrong things and makes them appear more attractive and appealing than the right things. “For God knows that when you eat of it (the fruit) your eyes will be opened, and you will be like God, knowing good and evil.” So when the woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was to be desired to make one wise, she took of its fruit and ate, and she also gave some to her husband who was with her, and he ate.” Genesis 3:5-6
DISCOURAGEMENT–Satan uses our problems and difficulties to depress us and make us give up. He tried this with Job. “Does Job fear God for nothing?” Satan replied. “Have you not put a hedge around him and his household and everything he has? You have blessed the work of his hands, so that his flocks and herds are spread throughout the land. But now stretch out your hand and strike everything he has, and he will surely curse you to your face.”
DELAY–Someone once said “if the devil can’t make you bad, he’ll make you busy.” He tries to make us put off doing what is good, so that we never do it at all. “Now listen, you who say, “Today or tomorrow we will go to this or that city, spend a year there, carry on business and make money.” Why, you do not even know what will happen tomorrow. What is your life? You are a mist that appears for a little while and then vanishes. Instead, you ought to say, “If it is the Lord’s will, we will live and do this or that.” ….If anyone, then, knows the good they ought to do and doesn’t do it, it is sin for them.” James 4:13-17
DIVISION–We are stronger together, so Satan seeks to separate us from other believers. In his letter to the Roman church, Paul says: ” I urge you, brothers and sisters, to watch out for those who cause divisions and put obstacles in your way that are contrary to the teaching you have learned. Keep away from them. For such people are not serving our Lord Christ…” Romans 16:17-18
The result of all these “D” words is another one: DISOBEDIENCE— and we all know what that leads to:
““For the wages of sin is death,” Romans 6:23a
Thankfully that’s not the end of the story–
“but the gift of God is eternal life in Christ Jesus our Lord” Romans 6:23b
Satan may deceive, divert, discourage, delay and divide, but he will not defeat us. God has the last word. We are more than conquerors through Him who loved us. (Romans 8:37)
