This an excellent devotional on defending oneself from Satan. We all need to be strong in the Creator of our faith…

Ephesians 6:10
Finally, be strong in the Lord, and in the strength of His might
The Christian’s Magna Charta of protection from Satan and his evil power is Ephesians 6:10-18. The first thing you should see in this passage about receiving God’s protection is that our role is not passive. God requires us to be active participants in the spiritual defense that He has provided for us. Notice how often we are commanded to take an active role (emphasis added):
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. For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places. Therefore, take up the full armor of God, that you may be able to resist in the evil day, and having done everything, to stand firm (verses 10-13).
You may be wondering, “If my position in Christ is secure and my protection is found in Him, why do I have to get actively involved? Can’t I just rest in Him and let Him protect me?” That’s like a soldier saying, “Our country is a major military power. We have the most advanced tanks, planes, missiles and ships in the world. Why should I bother with wearing a helmet, standing guard or learning how to shoot a gun? It’s much more comfortable to stay in camp while the tanks and planes fight the war.” When the enemy troops infiltrate, guess who will be one of the first soldiers to get picked off!
God, our “commanding officer,” has provided everything we need to secure victory over the evil forces of darkness. But He says, “I’ve prepared a winning strategy and designed effective weapons. But if you don’t do your part by staying on active duty, you’re likely to become a casualty.” You can’t expect God to protect you from demonic influences if you don’t take an active part in His prepared strategy.
Prayer: Lord, I choose to be strong in You today and actively stand in the strength of Your might.
Doubt? Or Unbelief? 
We Need the Good Shepherd
I know I have one of Neil Anderson’s books that I greatly appreciated years ago. It isn’t in my “current” bookshelf so I’ll have to look for it. These quotes from him have made me thirsty.
>> “Can’t I just rest in Him and let Him protect me?”
I certainly can’t say I ‘enjoy’ spiritual warfare, but I can assert that my spiritual growth would be lacking if it wasn’t for times of warfare. I praise God that I can look back on such times and see how my faith was strengthened through battles. If everything was done for us automatically, that wouldn’t happen.
Putting on my armour enables me to resist the devil and gives me the joy of seeing him flee at the sight of Christ to whom I have submitted.
What an amazing God!
Great comment Angela and right on point! No trials, no growth=stale Christian life.
