God is not the God of confusion, but of order.
Satan is the god of confusion. To get order out of chaos, God said: "Let there be light".
To get chaos out of order, Satan says 'Let there be confusion'.
His it is to confuse issues and elements.
To do this, he must - as the word suggests - fuse (or try to fuse) elements which are constitutionally different and do not belong to each other.
Thus there is a constitutional contradiction and inconsistency.
It is only when his master-method runs amok that we have utter and unmitigated wickedness.
His main work is deception by mixture.
It is just here that the place, meaning, and sovereignty of the Holy Spirit in the life of the child of God has its meaning and importance.
He is 'The Spirit of Truth'. He alone knows where truth ends and falsehood begins.
Only as we truly "walk in the Spirit" shall we know the truth and be made free from error.
A walk in the Spirit demands a 'circumcised heart', a heart in which the severance has been made between flesh and spirit, Christ and self.
There has never been a heresy that has not had in it sufficient truth to deceive very good people.
Likewise, there has never been anything wholly of God but the strategy of the Evil One has been to fasten on to it some implication, insinuation, interpretation, or suggestion, that would make it questionable or 'dangerous'.
He even did this with the LORD Jesus Himself.
He did it with Paul all through his life.
Let a demon-possessed girl in Philippi sponsor the preaching of Paul and Silas, and it is damned and discredited.
So, we come to this. A good thing can be made its own enemy, by being either confused, or taken out of its true meaning.
