The same came to him by night, and said to him, "Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do, unless God is with him."

 When that happens we are born of water and the Spirit. There are two thoughts there. Water is the symbol of cleansing. When Jesus takes possession of our lives, when we love him with all our heart, the sins of the past are forgiven and forgotten. The Spirit is the symbol of power. When Jesus takes possession of our lives it is not only that the past is forgotten and forgiven; if that were all, we might well proceed to make the same mess of life all over again; but into life there enters a new power which enables us to be what by ourselves we could never be and to do what by ourselves we could never do. Water and the Spirit stand for the cleansing and the strengthening power of Christ, which wipes out the past and gives victory in the future.
