Doing what God tells us to do is not as difficult as one might imagine, because the Lord God Almighty himself enables us to do his will. He tells the indwelling Holy Spirit Of God exactly what we need to do, in order to benefit from God's promises. When we fail to do what God is telling us to do, the devil gains control. It is as though we had told the devil that we would prefer to do his will, instead of God's will.
If the Lord God Almighty needs people who will never obey his will, he can simply pay a visit to hell, and choose any of the demons whom Satan desires to lend him. The Lord God Almighty needs individuals whose hearts are committed to obedience, and whose souls are fully surrendered to doing his will, regardless of the circumstances. There always will be individuals who seem to have a fully sourced argument to the contrary. If you let them win, and you implement their plan of action, you are likely implementing the devil's plan. The Lord God Almighty is a God of deliverance.
