Believe it or not, the title’s question above has an incredibly simple answer, but the things you must understand to grasp it are not so easy. Let us start with another question.
“Behold, the wicked brings forth iniquity; yes, he conceives trouble and brings forth falsehood. He made a pit and dug it out, and has fallen into the ditch which he made. His trouble shall return upon his own head. And his violent dealing shall come down on his own crown.” Psalm 7:14-16.
“Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour. Resist him, steadfast in the faith, knowing that the same sufferings are experienced by your brotherhood in the world.” 1 Peter 5:8-9.
