Charles Stanley - Fight Your Battles on Your Knees
We grow in faith by exercising it, by trusting God in situation after situation, circumstance after circumstance, relationship after relationship. We develop a personal history in which we obey God and He remains faithful in His loving care of us.
It is impossible for you to resist the devil for very long if you do not believe that Christ Jesus through you can and will defeat the devil. Furthermore, you can remain firm in your faith only when you completely submit to God—in all areas of your life. When you refuse to submit a problem or area to the Lord, you are saying, “I can handle this. I don’t need Your help.” That’s precisely what Satan wants you to do: trust your ability and not in omnipotent God. It is also the place where he will level his greatest attack against you!
