The primary way seeds of fear enter your mind is through one of the "gates" of your senses. Seeds of fear can enter through what you see, hear, feel, or even smell. For example, if you are in a crowded building and you smell smoke, what is your first thought?

The devil uses these seeds that enter through the sense gates to make suggestions. In fact, suggestion is one of his most potent weapons.

His tactic is to suggest certain words, certain scenarios, and certain possible outcomes - all with the intent of planting a seed of fear. All of this takes place in the form of thoughts.

The first thing you need to realize is that negative thoughts are going to come. It is inevitable. The solution is that you do not have to keep those thoughts. Instead of wasting spiritual energy in a futile attempt to avoid bad thoughts, we should refocus our minds on how to deal with those thoughts when they come.

Take It Or Leave It
You can take or refuse any thought, good or bad. What do I mean by "taking" a thought? Jesus told His disciples, "Why take ye thought for raiment?" (Matt. 6:28). Jesus made an important point with that comment. Thoughts are not forced upon you. They can be taken (accepted) or rejected. The choice is yours.

How is a thought "taken?" Jesus helped us out with this as well. He also said, "Take no thought saying, what shall we eat" (Matt. 6:31). According to our Lord, you "take" a thought when you open your mouth and speak out something based on that thought. Do not say something simply because it pops into your mind. When you say it, you take it.

Do not take those thoughts of doubt and fear. Reject them by refusing to speak them out. I am aware that it is easier to say this than to do it. Thoughts can be difficult to battle. But, you can neutralize a thought and render it harmless, long before it has ever had a chance to germinate, take root, and grow.

One of the most effective ways to silence a satanic suggestion or thought is to speak the opposite out loud, particularly when you can quote God's Word. Your mind cannot think one thing while your tongue is speaking something different. Try counting to 10 in your mind, and in the middle of counting, say, "Hallelujah!" You will find that your counting stops when you begin to speak.

If you catch the devil trying to suggest a fearful thought in your mind, respond immediately by speaking scriptures with your mouth.

Do not let fear of embarrassment keep you from speaking the Word out loud, even in public. So what if people think you are crazy? Remember what fear of people will do? Which is more important: your spiritual health and well-being or some stranger's opinion of you? You need to open your mouth and say the right things. God designed you so that your heart and mouth work together.

God has given us spiritual weaponry with which to battle the thoughts and suggestions of the devil. One of the most powerful of these weapons is "rebuking."

Just as with the previous suggestion, rebuking evil thoughts must be done with the spoken word. How do you rebuke a fearful thought? Actually, this is a simple thing to do. Just say, "In the name of Jesus, I will not have this thought in my mind! I have been delivered from fear!" Get aggressive and warlike when confronted with thoughts of fear.

Thoughts are powerful things. Give them enough time and attention, and they will have you doing and saying things you would never dream of doing and saying. "The devil made me do it," is a popular "cop out" when a Christian is caught in a sin. I have news for you! If you get caught up in sin, it is not because the devil made you do it.

More than likely, it is because you let thoughts turn into imaginations, and imaginations led to actions. No one gets "blindsided" by adultery. You do not get ambushed and find yourself in bed with someone else. If you succumb to adultery, it is because you invested time thinking about the possibility, imagining it, and fantasizing about it.

The devil will tell you, "A little fantasy won't hurt anything. It's not like you're really doing anything wrong." Do not fall for this thought. It is a lie.

Spend some time thinking about a sin, and I guarantee you that the devil will eventually present you with an opportunity to do it. Then, when you need the will to resist temptation, it is gone. You have no power to put down the act, because your thought life has been focused on sin. Thoughts invariably lead to actions.

I cannot over-emphasize how vital it is that you learn to deal with unholy thoughts. One of the best methods for doing so is found in 2 Corinthians:
Casting down imaginations, and every high thing that exalts itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ.
(2 Cor. 10:5)
What did Paul tell us to do in that verse? He said to "cast down imaginations." What kind of imaginations was he talking about?

We find out what kind of thoughts by reading the rest of that verse. We are to cast down those thoughts that do not line up with the will and Word of God. We are to measure every thought and every imagination that comes into our minds against the standard of God's Word and character. If a thought does not line up, cast it down!

Once you have arrested or cast down a fear-producing thought or imagination, it is important to take another step. When you remove something, you must replace it with something else. This is especially true when it comes to thoughts. Have you ever tried to think about nothing? It is impossible. The human mind does not work that way. When you remove an evil thought, you must immediately replace it with something else. Otherwise, the enemy will slip right back in with another evil thought.

What kind of thought should you put in place of a thought you have just arrested? Philippians has some good suggestions:
Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
(Phil. 4:8)
Your mind is like a computer. "Garbage in, garbage out," is what computer programmers say. Well, you can program your mind with things that are true, honest, just, pure, lovely, of good report, virtuous, and praise worthy. The more you do, the more likely you will be to respond correctly when the pressure is on.
