If you give the devil place, he will take it. You have to stay alert and keep your shield of faith high because if you don't, he'll turn around and steal back from you the ground you just took.
There have been people who have received their healing and have fallen back into their old thinking patterns of sickness. They let their faith down and gave the devil an opening. When he came along with an old symptom, they weren't ready for him. They fell victim to his counterattack.
You can stand successfully against the devil's strategies! But before you do, you're going to have to make three quality decisions.
First, you must make the Word of God the final authority in your life. Line up your thinking with whatever the Word says.
Next, you must decide to live your life by faith in what God has said. The Bible says, "Faith comes by hearing, and hearing by the Word of God" (Romans 10:17, New King James Version).
Finally, you must decide to live by the love of God because faith works by love. Without love, your faith won't function. Without the Word, you can't have faith. So don't try to make one of these decisions without the other two. You need to make all three of them. This lifestyle of the Word, faith and love keeps you in a place of resistance to the devil!
I suggest you get alone with God and pray:
In the Name of Jesus, I commit myself from this day forward to live by the Word of God, to live by my faith, and to live by the love of God.
Decide today to give the devil no place!
