From April 13-15, 2015, around six thousand Christian men and women came together in Orlando, Florida, for The Gospel Coalition’s 2015 National Conference, to consider the new heavens and the new earth. Yesterday, I shared three personal reflections on the conference, and today, I wanted to share a few of the standout moments from the plenary sessions:
1. John Piper on Christians as radical truth-tellers. As Piper applied his texts, Isaiah 11 and Isaiah 65 (the whole message was terrific), he declared that Jesus is “calling us to be people of radical truthfulness. To not make judgments on appearances, but on truth.… We are to be radically truth-driven Messiah people.”
His key example? Ghostwriting among Christian authors:
“If you write something, put your name on it! If you didn’t don’t put your name on it! If someone wrote it with you, put both names on it. We do not use the ways of the world to write a book or win a soul!”
2. Keller on what a circumcised heart is. “When the Bible talks about the heart it’s the control center of the whole being. Hearts put their trust in something. They face things. … The thing your heart looks to is what you think about when you don’t have anything to think about. What the heart wants, the mind finds reasonable, the emotions find desirable.”
And this is why God commands us to have circumcized hearts. This, external sign of being obedient to the law of God. Circumcision of the heart, he said, “means that the innermost will wants to do those things. Our pleasure and our duty are the same. What you ought to do and what you want to do are the same things.”
But it’s the illustration he gives about why God commands that particularly intimate part of the body be involved in physical circumcision that got me. It’s to remind us of the grossness, the vileness of sin.
3. Ligon Duncan on why the “not yet” matters right now. Most Christians are familiar with the idea of the already/not yet, or the now and not yet of reality. The gospel has present affects, but has future implications. And yet, so many people seem to think that if you pay too much attention to the “not yet” you’re good for nothing right now. As he preached on Romans 8:16-25, Duncan politely called bunk on this idea. “There are a lot of people who say if you care about the ‘not yet’, you won’t care about ‘now’, and you’ll be escapist in your view of the Christian life. But the Bible says that the ‘now’ matters forever, and ‘forever’ matters right now.
You must have your eye on that future hope. If you’re just hoping in the now, you’re not hoping as Paul is telling you to hope. The reformed doctrine of justification in grace alone by faith alone in Christ alone ended slavery in the British empire. We’ve been told our doctrine isn’t “social” enough. We need to modify it to make it more social. No.
It is the doctrine of justification in grace alone by faith alone in Christ alone that caused Wilberforce and his coworkers to expend their last breath to set captives free! You can’t live now unless your hope is in the not yet. The now is so overwhelming, if you really look at it, you can’t survive without the not yet.1
(Sadly there’s no clip of this available, but it was great.)
