The Answer from God’s Word:
Because God has become flesh, Satan has employed all sorts of methods of accusation, wanting to attack God this way. However, God does not retreat because of this—He just speaks and works among mankind and allows people to know Him through His incarnate flesh. Satan is red-eyed with fury and has put forth a great deal of effort on God’s people to make them negative, retreat, and even lose their way.

What God wants to do in man is just what Satan wants to destroy, and what Satan wants to destroy is expressed through man without being hidden at all. What God does in people has clear demonstrations—their conditions are getting better and better. Satan’s destruction in mankind is also clearly represented—they are more and more depraved and their conditions are sinking lower and lower. If it’s dire enough, they could be captured by Satan.

1. God works to make man understand more truths and know more about God’s disposition. In the end, man gains knowledge of God and is willing to die for God and live for God. But those weaknesses in man are still in the control and grasp of Satan, which can still make man suffer. Evil spirits can still work on man to disturb him, causing him to be out of his senses, disordered in his mind, upset in his heart, or disturbed in every respect. There are still things of mind and soul within man that can be controlled and manipulated by Satan.
2. So, you may have sicknesses and worries and may possibly seek death or hang yourself. And you may also feel the world is desolate, and feel it is meaningless to live. That is to say, these sufferings of man are still in Satan’s grasp. This is man’s fatal spot. This is man’s fatal spot.

In every step of work that God does within people, externally it appears to be interactions between people, as if born of human arrangements, or from human interference. But behind the scenes, every step of work, and everything that happens, is a wager made by Satan before God, and requires people to stand firm in their testimony to God. Take when Job was tried, for example: Behind the scenes, Satan was making a bet with God, and what happened to Job was the deeds of men, and the interference of men. Behind every step that God does in you is Satan’s wager with God—behind it all is a battle. … When God and Satan do battle in the spiritual realm, how should you satisfy God, and how should you stand firm in your testimony to Him?
