"Now the serpent was more cunning than any beast of the field which the Lord God had made. And he said to the woman, "Has God indeed said, 'You shall not eat of every tree of the garden'?" Gen 3:1 NKJV
Look out for the deliberate perversion of the Word....it is the work of the Lord's enemy. Know the Word. Study the Word. Renew your mind with the Word, and use it to strip the enemy of his deceitful ways. He only has power when you allow him to trip you up and doubt what you know to be true.
