“But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ.” (2 Corinthians 11:3).
Read it carefully what this verse states, as the Serpent beguiled eve(devil in that beast, the intelligence, who can give logic and also perform reasoning), now we would not be(or is) deceived by any serpent, at present time Devil will not use any Serpent(the animal) to deceive us but He had already deceived Eve and took over the authority of the whole Human Kind, now we have two different minds in us, the Knowledge of Good and Evil(the carnal Mind, which is stored information, on the basic the good and evil is decided) and another is Spirit Mind the Mind of Christ( see everything with faith and nothing worry, no hanging between good and evil).
As everybody is wise enough in their own eyes they would not take it and they may miss it. But as Paul said, I fear that, your Mind would be corrupted (takeover by anything, unusable, not able to perform anything), and you cannot see the simplicity which is in Christ.
For being the one who can see the simplicity in Christ, there is only one way, which is to get rid of the thoughts which are in the mind( carnal mind), Dare to believe the I am nothing, I don’t know anything, and try to empty your mind and Heart, so that the new things can be kept in the treasure of Heart.
This all is impossible for a man, but with God everything is possible. So pray for having His spirit, He is still calling and being able to see the Simplicity and become the image of Christ.
