When a man or woman is truly honest (not just working at it) it is virtually impossible to insult them personally. There is nothing there to insult. Those who were truly ready for the kingdom were just such people. Their inner poverty of spirit and rigorous honesty had set them free. They were people who had nothing to be proud of.
Then יהושע said to His taught ones, “If anyone wishes to come after Me, let him deny himself, and take up his stake, and follow Me.
For whoever wishes to save his life shall lose it, and whoever loses his life for My sake shall find it.
For what is a man profited if he gains all the world, and loses his own life? Or what shall a man give in exchange for his life?”
