Methodism's John Wesley was already 35 years old when he brought himself into contact with the Moravian missionaries in London. Many years earlier he had finished his studies. He had long ago learned history and philosophy and many languages. He had been ordained a priest years earlier. But now, at age 35, he first discovered his spirit-being "strangely warmed." The message of God's love had penetrated his mind in such a way that - with a third of his earthly life already over - he was now a changed person. That personal experience shaped the remaining two-thirds of his years upon this earth.

That is what Jesus was talking about when he met with Nicodemus.
