In this age, just prior to the second coming of Christ in the clouds of heaven, such a work as that of John [the Baptist] is to be done. God calls for men who will prepare a people to stand in the great day of the Lord. . . . In order to give such a message as John gave, we must have a spiritual experience like his. The same work must be wrought in us. We must behold God, and in beholding Him lose sight of self.
2 Corinthians 3:18
But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.
