Transcript from a panel discussion at the 2010 West Coast Ligonier Conference, Christless Christianity:

Questioner (Chris Larson): Doctor Sproul, if Jesus is 100% human and tempted in every way we were, does that mean he inherited a fallen nature from the fall?

R.C. Sproul: No.

Chris Larson: Could you elaborate?

[laughter]

R.C. Sproul: The first place is that Jesus is not 100% human. His human nature is 100% human. But He also has a divine nature which is 100% divine. Okay, so He has two natures, one person. Let’s start there. But the question really is getting at, if He’s in his human nature, 100% human, wouldn’t that necessitate that He’d be born with original sin? That’s what the question is, isn’t it? Because all human beings, after Adam, are born in that condition. This is the second half. And Adam was 100% human before he fell. And we will be 100% human in heaven without sin. So, sin is not a necessary condition for humanness. It is the universal condition of Fallen Humanity. No question about that. But Jesus came into the world without original sin and lived the life of perfect obedience, which was the foundation for the righteousness that is imputed to us in our justification. This is one of the things scares me to death in this whole thing that we’re going through now is the assault on the perfect active obedience of Jesus. It’s coming out of certain evangelical quarters. We have evangelical professors and evangelical institutions attacking the idea of Christ’s perfect active obedience. That’s a disaster to biblical Christianity. I hope I’ve answered the question. Jesus could have a pure perfect humanity without original sin.
