Well there you go then, only God can discern your fruits of your true spirit.
The Most High knows where we will ultimately end up, but He has charged every one of us to test every spirit that we encounter - to determine, based on its fruits, whether or not it is substantive.
If Christians aren't looking at persons, and judging them by their fruits, then they are being deluded - as any deceiving spirit can come to them because
they do not watch.
Likewise, only the people who
do not watch do not know the day or hour of the coming of the Son of Man. Religion has lead many people astray, but ultimately every person has a responsibility to themselves, and to the Most High. This includes discernment.
In fact, discernment is considered a spiritual
gift. And, people who treat others like Columbians treated American slaves and natives exhibit rotten fruit - therefore their declaration of being a Christian is a deception, or foolishness. I know nearly everyone thinks you can murder someone and still be a Christian as long as you claim it - which is fine to believe if you want to be deceived about the Most High.
Neither the Most High, nor the Son of the Most High would enslave humans, call them animals, tell them it was their fate to be slaves, genocide an entire people because of lust for land, and continue to subjugate the same people while claiming they have had no subjugation. Anyone who does these things and calls themselves a Christian is a liar, just like anyone who loves to do evil but claims righteousness is a liar. It is very simple spiritually; religion and dogma have trapped the minds into the diminutive thinking machines they have become for humanity.
