Belshazzar, while engaged in his sacrilegious feast, was not aware that he had guests he had not invited. The God of heaven heard the praises bestowed upon vessels of gold and silver. He saw the desecration of that which had been dedicated to Him by holy consecration applied to profane and licentious purposes. It is a truth which should make every one of us weep, that those living in these last days, upon whom the ends of the world are come, are far more guilty than was Belshazzar. This is possible in many ways. When men have taken upon themselves the vows of consecration, to devote all their powers to the sacred service of God; when they occupy the position of expositors of Bible truth, and have received the solemn charge; when God and angels are summoned as witnesses to the solemn dedication of soul, body, and spirit to God's service—then shall these men who minister in a most holy office desecrate their God-given powers to unholy purposes? Shall the sacred vessel, whom God is to use for a high and holy work, be dragged from its lofty, controlling sphere to administer to debasing lust? Is not this idol worship of the most degrading kind?—the lips uttering praises and adoring a sinful human being, pouring forth expressions of ravishing tenderness and adulation which belong alone to God—the powers given to God in solemn consecration administering to a harlot; for any woman who will allow the addresses of another man than her husband, who will listen to his advances, and whose ears will be pleased with the outpouring of lavish words of affection, of adoration, of endearment, is an adulteress and a harlot. TM 434.1
No misfortune is so great as to become the worshiper of a false god. No man is in such miserable darkness as he who has lost his way to heaven. It seems that an infatuation is upon him, for he has a false god. To turn this worship of the human, fallen, corrupt beings of earth to the only true object of worship seems a hopeless task. There are in our time continual repetitions of Belshazzar's feast and Belshazzar's worship; and Belshazzar's sin is repeated when the heart, which God requires to be given to Him in pure and holy devotion, is turned away from Him to worship a human being, and the lips are made to utter words of praise and adoration which belong alone to the Lord God of heaven. When the affections God claims to cluster about Him are made to center upon earthly objects,—a woman, a man, or any earthly things,—God is superseded by the object which enchains the senses and affections, and the powers which were solemnly dedicated to God are bestowed upon a human being who is defiled with sin. Men and women who once bore the image of God, but are lost by disobedience and sin, He means to restore again through their becoming partakers of the divine nature, having escaped the corruption which is in the world through lust. And when men and women devote their God-given powers to unholy purposes, to minister to lust, God is dishonored, and the actors are ruined. TM 435.1
When engaged in man-and-woman worship, remember that there is the same witness present as at the feast of Belshazzar. On that occasion, when in the very midst of their revelry, when God was forgotten, when the carnal senses were inflamed, a thrill of terror rushed through every soul. The cup that was being praised and idolized by the king fell from his nerveless hand, and in the language of the Spirit of God, his “countenance was changed, and his thoughts troubled him, so that the joints of his loins were loosed, and his knees smote one against another.” A mysterious, bloodless hand was seen tracing characters on the wall. These mysterious fingers belonging to and guided by an unseen power wrote the fully as mysterious characters, which were unintelligible to the awe-stricken revelers. A light like the lightning followed the forming of every letter, and lingered there, making them living characters of awful and terrible significance to all who looked upon them. “Mene, mene, tekel, upharsin.” Their very ignorance of those letters traced upon the wall, standing there flashing with light, sent terror to their sinful hearts. Their aroused consciences interpreted these letters to be a denunciation against them. Suspicion, fear, and alarm took hold upon king and princes. TM 435.2
Belshazzar, awed by this representation of God's power, showing that they had a witness, though they knew it not, had had great opportunities of knowing the works of the living God, and His power, and of doing His will. He had been privileged with much light. His grandfather, Nebuchadnezzar, had been warned of his danger in forgetting God and glorifying himself. Belshazzar had a knowledge of his banishment from the society of men, and his association with the beasts of the field; and these facts, which ought to have been a lesson to him, he disregarded, as if they had never occurred; and he went on repeating the sins of his grandfather. He dared to commit the crimes which brought God's judgments upon Nebuchadnezzar. He was condemned, not alone that he himself was doing wickedly, but that he had not availed himself of opportunities and capabilities, if cultivated, of being right. TM 436.1
