Eric Redmond has posted an excellent piece on the prerogative of God and the interpretation of Luke 13:1-9. This passage received much attention in light of the not-too-long-ago tragedy of the bridge collapse in Minneapolis. Eric writes:
"As a pastor who loves his people, I can only preach of a God who is free to do all things as the Eternally Good God. I cannot promote a God who is limited by anything or who grants unrestrained freedom to creatures that are sinful. To do so would make for a worse calamity than the collapse of a bridge. We would instead collapse upon ourselves the very right of God to be God".
