Iron sharpening iron & spiritual warfare have NOTHING in common.
We are now in the Falling Away of 2Thess 2, with millions being deceived & deluded with false doctrines of all sorts.
If I could guess the ratio, I think the deceived church outnumber the true church at over 100 to 1.
Then again, it could be way higher than that.
Jesus is coming, & most aren't talking about it.
When the Son of Man comes, will He find faith on the earth?
