Let us remember that the Apostles, or their disciples never took their eyes off of deception, or the wolf, lest it creep into the church and devour. [ and sometimes it did...].
I often , as a young man, had similar experiences. It was though I could gauge the pressure upon me, when I would read about, or think about error, and false teachers and prophets. David wrote:"I have not concerned myself with things too high for me."
Sometimes wicked doctrines are accompanied by wicked spirits. As odd as it sounds, I know of some people who have shipwrecked , fell away, by dabbling with odd doctrines on the Internet. One of them, a former friend of mine, became a strong Universalist by going to sites on the Internet. I once considered him a strong Christian.
This group believes that Satan and all the demons, and every living soul ever created will be saved. Hell, is but purifying fire to purge the unrepentant of sin. Wow!...but think about it. My friend is now baptised in this belief system, and is no longer a believer in Christ.
Words, or thoughts cannot change a man's inner being. There are things ATTACHED to particular thought patterns in the spirit realm.
Consider Mormonism; Magic glasses, golden scrolls, and Angels bearing another gospel.........It is totally fantastical...with many glaring inconsistencies....yet the belief in this bizarre worship structure has brought millions into one mind.....and it is adamantly opposed to the Savior,His blood, ad His Godhead.
The bible calls them "Doctrines of Demons", and is it strange that we would not believe that the same demons who construct these lying patterns would not be there to anoint them, as we encounter them....to try and place them at the core of your spirit?
I will also add this. All overcoming warfare is accomplished in the Throne of Jesus. Our victory begins and ends with Him alone. We cannot receive light or power unless we are connected to the Throne of Power and light. We see and understand within our spirits, not our intellect. This is at the heart of all true Godly discernment.
Reading the Psalms , and understanding that David, dealt with the exact warfare that we in the Church does, will help. David wrote, "My enemies are stronger than I.",....along with, "You are greater than the sum of all things!"...."Power belongs unto God!"...and well understood that through God, all of his enemies are but a drop in the bucket...chaff in the wind.
Satan and all of his demons multiplied are as nothing before the Father; and that God is just allowing Satan to rage for a while, until HIS purposes are fulfilled. When we say that Jesus is Lord, we are saying that He is Yahweh, with all of His infinite power.
"With all of your getting, get understanding!" Worship and warfare are integrally meshed, and our winning is always wrought in His Peace......but there is struggle, and the battle is real and awful.....it must be so.
