What he said.

Jesus did not say, "Go and sin no more, and then your sins will be forgiven." Jesus said...

"Woman, where are they? Has no one condemned you?"

"No one, sir," she said.

"Then neither do I condemn you," Jesus declared. "Go now and leave your life of sin."

There's a pretty big difference here. The first example is all about the Law. The second example is about the Gospel...but it's also about the Law, so it's about both the good news and the bad news. And that is what Jesus is about: the Good News as well as the bad.
