Early in Genesis, Yahweh asks Cain where his brother Abel is. Cain, like a punk, replies, "I don't know. Am I my brother's keeper?" (P.S. He also killed Abel) God's response indicates that, yes, Cain is supposed to be his brother's keeper. But I wish the Almighty had been more explicit; that the story would have put it in all bold and all capital letters "YES! YOU ARE YOUR BROTHER'S KEEPER! AND YOUR SISTER'S TOO!" so that no one could ignore the reality that we are called to take care of one another.
I thought about Cain's flippant response when the news was announced that the president was pulling the country out of the Paris Climate Accord. The move was unfortunately not surprising as it fits his "America First" agenda and also considering his earlier statements that climate change is a hoax. Still, the move was infuriating.
