The devil is only strong when man is weak.

Man is weak when, instead of using his reason, he uses his emotions.

The emotions of the heart enslave and always lead to poor choices.

The Spirit of God becomes helpless in the lives of those who turn away from the practice of His advice.

The truth only sets free those who put it into practice.

The large quantity of oppressed or depressed evangelicals is proof of this.

For the eyes of the Lord run to and fro throughout the whole earth, to show Himself strong on behalf of those whose heart is loyal to Him… 2 Chronicles 16.9

The LORD God only exercises His power in favor of those who obey Him;

The others, like Cain, see this and are envious.
