In Spectacular Sins, John Piper works hard to make a case that God is in control and therefore he actually ordains sin for his own purposes and brings about natural disasters as judgement. I strongly disagree. Here's what we do know: Even the most horrible things in our lives can be turned for our good and used for God’s glory. Not that He willed it, but surrendering it all to Him, He takes a pile of garbage and filth and turns it for His glory and for our GOOD!
