Satan trembles when he knows your faith is firm and strong, but if it is tottering and trembling, then he sounds the note of triumph and seeks to lead on his hosts to make a full end of you because you are beginning to relax your grip of your shield.

Charles Spurgeon

Put on the whole armor of God, that you may be able to stand against the wiles of the devil.   Ephesians 6:11

Above all, take the shield of faith with which you will be able to quench all the fiery darts of the wicked one.  Ephesians 6:16

Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour.  1 Peter 5:8

Therefore submit to God. Resist the devil and he will flee from you.  James 4:7

In God I have put my trust; I will not be afraid. What can man do to me?           Psalm 56:11
