“If a miracle of heart was worked that turns the murderers into the exact opposite life savers would you STILL disdain the gift of the Lord?”
I wouldn’t.
Saul of Tarsus—Paul—was essentially a mass murderer too. But found salvation thru Jesus and did His bidding.
These cases are not easy to navigate.
But Jesus is not easy to accept, either. We have to let Him push our pride aside. He will be exceeding patient and exceeding merciful as He does so... but the need to do it is most 100% non-negotiable.
And once He has done so, He will replace that pride with His own glory, and when we are really versed in it, that pride will look like the little runtly thing it always was.
