I've been reading responses on social media and here to the news of his death. His life and beliefs are getting heavily assailed, not surprisingly, by atheists (saw much nastiness from atheistic readers of online BBC news and The Guardian through Facebook links), and Calvinists.
I've spent a lot of time reading online debates (I actually read much more than I engage), and what I've observed with a shocking degree of consistency, is that most atheists and Calvinists have a surprisingly similar spirit: they usually feed on aggressively criticizing those who disagree with them, and both seldom show the fruits of the spirit (love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control) -- let alone much humility.
Remember what Paul said: having all the knowledge in the world (atheists and Calvinists often exhibit great head knowledge), without having love, makes us nothing.
Billy Graham may not have had all the knowledge. But he proclaimed Christ, and he exhibited the fruits of the spirit more than the majority of those from the other groups I have seen.
I'll leave the hair-splitting to everyone else. Or best yet, we should leave it to God, Who alone knows where Graham's spirit resides.
