Submit yourselves therefore to God. Resist the devil, and he will flee from you.
James 4:7
"The adversary of souls is not permitted to read the thoughts of men; but he is a keen observer, and he marks the words; he takes account of actions, and skillfully adapts his temptations to meet the cases of those who place themselves in his power.
If we would labor to repress sinful thoughts and feelings, giving them no expression in words or actions, Satan would be defeated; for he could not prepare his specious temptations to meet the case."
E.G.W.
