time signature carry on wayward son 4/4
Yes, it's 4/4, fairly boring for Kansas. There are lots of other Kansas songs to pick if you want 11/8, 13/8, 7/8, 9/8, 5/4, or whatever unusual time signature you need. You probably have all of those and more just in The Spider, and that's only like three minutes long.
must be a Christian Hedonist to be saved
This one amazed me. It led to some people taking Piper way out of context. He says that you need to find joy in what God has done in Christ before you can receive it, which is just astoundingly obvious. How could someone receive the gift of God while finding it horrific? These people think Piper is teaching that you need to have an explicit affirmation of the thesis of Christian hedonism to be saved, which isn't even close to what he says. Piper is making a very small point. He thinks Christian hedonism is true, and he thinks those who have accepted the Christian gospel and repented of their sin are living as Christian hedonists to some degree, even if they pretend they aren't. So when someone asks him if you need to fulfill your desires in God to be saved, of course he'll say yes. To paint him as if he's saying that someone can't be saved without affirming the words that he uses to describe Christian hedonism is simply bearing false witness against him.
