agonus: "Let the dead bury their dead"...
There will be a cut-off point. Like an old Baptist song I heard ..."when the trumpet blows and time shall be no more!"
But I think Clint is holding out a "last call" opportunity for your loved ones. When you do make that final, last effort...you will know if there is any indication that a relationship can be salvaged or whether it is totally a lost cause. Then, you can walk away with your head high, without guilt, without regret, that you did all you could and the fault lies not with you.
If you see that the relationship is beyond resolution, you don't beat a dead horse.
Clint is not advising anyone to convince their loved ones through words, debate, or revelation of the evils within WT. He advocates just being there and showing affection through ACTIONS, not words. Let's see which will speak louder.
In the video, he mentions "natural affection." You will remember the scripture that 'in the last days, there will be those without natural affection'. This is exactly what the WT is promoting by separating families through shunning. It is a natural affection that parents should love their children--no matter what! And children should love their parents--no matter what! This natural affection is destroyed by WT dictates. Maybe your loved ones will be disturbed when they begin to realize this. Let your actions speak for you.
