El-Satan is very slick; but he doesn't know what we are thinking, unless he is the catalyst behind our thoughts. He plants thoughts that are called an Idea, which is not in the King James Version of the Bible. Our LORD requires revelation, wisdom, and obedience. Not trickery.
The first words to Eve, from the Tree of Knowledge of good and evil, were: "Yea, has God said." This is a setup, and data-mining. Satan planted the Idea of what was to follow. He is the ultimate con-artist.
The world believes that "small people talk about other people: average people talk about things: great people talk about Ideas". This is not how the Kingdom of Heaven operates on earth. The Kingdom is at the intersection of our eyes, and our ears. Our choice is Christ Jesus, period.
We are taught what to meditate on. We must get Truth in us, and seek Truth, in order for the Holy Spirit to bring it back to our remembrance. The world systems are designed by demons and the Children of Cain, to re-direct our worship.
Class Ideas, and random thoughts that pop into our minds, together. Idolatry has always, and always will be forbidden. Trust in the LORD with all of our might, lean not to our understanding - but His. Establish ourselves on Righteousness, which is the solid Rock. The LORD knows how to protect His own. REBUKE an Idea, for what it is.
