God had called the son of Zacharias to a great work, the greatest ever committed to men. In order to accomplish this work, he must have the Lord to work with him. And the Spirit of God would be with him if he heeded the instruction of the angel.
John was to go forth as Jehovah’s messenger, to bring to men the light of God. He must give a new direction to their thoughts. He must impress them with the holiness of God’s requirements, and their need of His perfect righteousness. Such a messenger must be holy. He must be a temple for the indwelling Spirit of God. In order to fulfill his mission, he must have a sound physical constitution, and mental and spiritual strength. Therefore it would be necessary for him to control the appetites and passions. He must be able so to control all his powers that he could stand among men as unmoved by surrounding circumstances as the rocks and mountains of the wilderness.
In the time of John the Baptist, greed for riches, and the love of luxury and display had become widespread. Sensuous pleasures, feasting and drinking, were causing physical disease and degeneracy, benumbing the spiritual perceptions, and lessening the sensibility to sin. John was to stand as a reformer. By his abstemious life and plain dress he was to rebuke the excesses of his time. Hence the directions given to the parents of John—a lesson of temperance by an angel from the throne of heaven.
In childhood and youth the character is most impressible. The power of self-control should then be acquired. By the fireside and at the family board influences are exerted whose results are as enduring as eternity.... The habits established in early years decide whether a man will be victorious or vanquished....
As a prophet, John was “to turn the hearts of the fathers to the children, and the disobedient to the wisdom of the just; to make ready a people prepared for the Lord.” In preparing the way for Christ’s first advent, he was a representative of those who are to prepare a people for our Lord’s second coming. The world is given to self-indulgence. Errors and fables abound. Satan’s snares for destroying souls are multiplied. All who would perfect holiness in the fear of God must learn the lessons of temperance and self-control. The appetites and passions must be held in subjection to the higher powers of the mind. This self-discipline is essential to that mental strength and spiritual insight which will enable us to understand and to practice the sacred truths of God’s Word. For this reason temperance finds its place in the work of preparation for Christ’s second coming (The Desire of Ages, 100, 101). LHU 363
This name is hallowed by the angels of heaven, by the inhabitants of unfallen worlds. When you pray, “Hallowed be Thy name,” you ask that it may be hallowed in this world, hallowed in you. Pr 293
"For he shall be great in the sight of the Lord, and shall drink neither wine nor strong drink; and he shall be filled with the Holy Ghost, even from his mother's womb." Luke 1:15 (King James Version)
