“There are some who doubt the efficacy of prayer; they argue thus: We must assume that a certain good thing has been either decreed or not decreed in favour of a certain person: if it has been decided, prayer is not wanted; and if it has not been decided, how can prayer effect a change in the Will of God, who is unchangeable? Neither righteousness in action, nor prayer, is of any avail in procuring any good thing that has not been ordained, or in escaping any evil that has been decreed. This is also the argument of Job in chap. xxi. But the answer to these arguments is this: Whatever may have been decreed, certain conditions must be fulfilled before the decree is executed. If a good harvest is decreed to a certain person, he must plough and sow before he can secure such a harvest; if punishment is decreed against him, the punishment is not inflicted in the absence of continued and repeated sinning. The history of King Ahab shows that the evil decreed against any sinner takes no effect if the sinner repents and is turned into another man. The change that takes place in man himself is the direct effect of prayer and righteousness; it prepares and qualifies him for receiving benefits and protection from evil. Our Sages say therefore: Prayer has its good effect both before and after the Divine decree. The Immutability of God is not less consistent with Efficacy of Prayer than it is with His knowledge of things which are possible, and may happen or may not happen. God and His knowledge being unchangeable, everything must be certain and nothing merely possible. And yet we are convinced of the existence of these things, and believe at the same time in the Immutability of God’s knowledge. In the same manner we are convinced of the Efficacy of Prayer without doubting the Immutability of God’s Will.” On Revelation, p. 46. The term ‏נביא‎ “prophet” only expressed the prophet’s function of addressing his fellow-men when inspired and impelled by the Spirit of the Lord. The verb “to prophesy” is therefore in Hebrew expressed by the nifal or passive. In so far as the Word of God has been revealed to him he is called ‏ראה‎, ‏חוזה‎ and ‏צפה‎ “Seer,” ‏איש אלהים‎ “Man of God,” ‏איש הרוח‎ “The inspired.” In the time of Samuel the title ‏ראה‎ was generally given to the prophet instead of ‏נביא‎ (1 Sam. ix. 9), as his advice was also sought by many who believed him to be able to foresee coming events and to know everything. As, however, the word ‏נביא‎ only describes the prophet as addressing his fellow-men, it is used both of the true and the false prophets, and also of teachers and preachers generally. The Targum on the Prophets (Jer. xxix. 15; Isa. xxix. 10) renders, therefore, the term ‏נביא‎ in some instances: ‏מלפין‎ “teachers,” ‏ספריא‎ “scholars.”
