Conversion [to Jesus Christ] may be a crisis; it may be a process. Even a crisis like birth is really a process…It would be stupid to argue whether birth or growth is the more important element in our experience. We are born to grow. And so it is in the Christian life. Some can remember the date of their conversion. Others cannot. What does it matter? Some people know their birthdays. Others do not. And none of us would know if our mothers had not told us! The important thing is not the date of birth, known or unknown, but whether or not we are alive.
