Even in justification, many Christians who are perfectly orthodox in doctrine look back upon their justification as though it were the end of all, at least until death comes. It is not. Birth is essential to life, but the parent is not only glad for the birth of his child. He is thankful for the living child that grows up. Whoever saw a couple get engaged simply because they wanted to enjoy the marriage ceremony? What they want to do is to live together. So it is with becoming a Christian. In one way you can say that it the new birth is everything; in another way you can say that really it is very little. It is everything because it is indispensable to begin with, but it is little in comparison with the living existential relationship. The legal circle of justification does not end statically; it opens to me a living person-to-person communication with the God who exists.
