As Jeremiah grew older he began understanding some of what was happening around him. He saw the foreigner, widow, and orphan abandoned. He saw people rejecting God’s way of love for their own twisted sense of self love.
Loving your neighbor means acting justly and loving mercy and that’s a big umbrella. It doesn’t just cover those you call your own. It covers those you don’t call your own too. The fatherless, the widow, the stranger.
One thing is absolutely clear about this story. You cannot fully love God without loving people. This is what Jesus means when he says he desires mercy, not sacrifice.
