We will notice in the second place the purpose of all these visions which have come to us. Paul was not permitted to dwell on the vision of truth which came to him. God had a purpose in its manifestation, and that purpose was revealed when He said to the wonder-stricken servant, "Arise; for I have appeared unto thee for this purpose, not that thou behold the truth for thyself, but to make thee a minister and a witness both of that which thou hast already seen and of other truths which I shall reveal unto thee. Go unto the Gentiles. Give them the truth which thou shalt receive that their eyes may be opened, and that they may be turned from darkness to light; that they, too, may receive a like inheritance with thyself...." This, then, is God's lesson to you and to me. He opens before our eyes the vision of a great truth and for a moment He permits our wondering gaze to rest upon it; then He bids us go forth. Jacob of old saw the vision of God's messengers ascending and descending, but none of them standing still. Herein, then, lies the secret of the success of the reformer. First the vision, then the purpose of the vision. "I was not disobedient unto the heavenly vision." This is the manly and noble confession of one of the world's greatest reformers, and in it we catch a glimpse of the secrets of the success of his divinely-appointed mission. The difference between the Saul of Tarsus and Paul the Prisoner of the Lord was measured by his obedience. This, too, is a universal law, true of the life of every reformer, who, having had revealed to him a vision of the great truth, has in obedience to that vision carried it to humanity. Though at first he holds the truth to himself, and longs to be lifted up by its power, he soon learns that there is a giving forth of that which one possesses which enriches the giver, and that the more he gives of his vision to men the richer it becomes, the brighter it grows, until it illuminates all his pathway....
