Matthew 7:6 "Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you."

Which, when used with the following:

John 6:44 "No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day."

Seems to point to the idea that the most one should do is lead by example, and if God wants those around to be drawn to that light, will nudge their heart in that direction. In the confusing paradox of the free will/predestination dilemma, one can see examples of this as far back as Moses. God hardens Pharaohs heart each time Moses is sent to ask for freedom, each hardening causing pain and suffering on the peoples of Egypt. One can see that Pharaoh was not allowed to say yes, his heart being hardened not to.

I could go on, but I could tell you were asking rhetorically. I guess I'm as guilty as they are, lol. Hopefully they might read my response to your rhetorical question and ponder on the path forward understanding that examples shown as light are what their faith calls for, not what they are doing which calls for their message to be trampled underfoot.
