How long you continue in this night of the soul will depend upon a number of factors, some of which you may be able later to identify, while others will remain with God, completely hidden from you. The words ?The day is thine, the night also is thine? will now be interpreted for you by the best of all teachers, the Holy Spirit; and you will know by personal experience what a blessed thing is the ministry of the night. But there is a limit to man?s ability to live without joy. Even Christ could endure the cross only because of the joy set before Him. The strongest steel breaks if kept too long under unrelieved tension. God knows exactly how much pressure each one of us can take. He knows how long we can endure the night, so He gives the soul relief, first by welcome glimpses of the morning star and then by the fuller light that harbingers the morning.
