God expects us to love the unlovable, do good to those who abuse us and spitefully use us, persecute and execute us, lead us as sheep to the slaughter all day long. That’s a tall order. Does He show the way, or does His mercy come to an end upon the physical death of the human being who never knew Him?
When we die and “go to heaven,” will we rejoice in the torments of the damned because they glorify God? Will we become like God in this? Or if God’s like that, do we WANT to become like Him?
Please do keep in mind the above when responding to those who agree with the second paragraph, btw. We wouldn’t want to be unloving either. My thesis is that most of these folks don’t think things through and don’t see that the things they say they believe go against the love they actually hold in their hearts from God. With notable and sad, sad, sad exceptions, of course, but even these are TRYING to honor God the best they can.
So yes, show the other guys they’re wrong – but do it nicely.
