Another very important feature of this subject consists in the fact, that there always have been in every gospel dispensation labors to perform of a practical character, such as the building of temples, the gathering of Israel out of Egypt, the building of the Ark of the Covenant, etc., none of which could be accomplished except by direct revelation from God. We may therefore conclude that while the ordinances and doctrines of the gospel are eternal and unchangeable, the circumstances associated with the people in every dispensation of the gospel are constantly changing. The emergencies of this situation must be met, not by the dead letter of ancient Scripture, but by present inspiration and revelation given through living oracles of God. "By a prophet the Lord brought Israel out of Egypt, and by a prophet was he preserved." (Hosea xii:13.) The prophecies of the Jewish prophets in the Old Testament, pointing to the advent of the Messiah, are clear and explicit. Read the seventh chapter of Isaiah, fourteenth verse; the ninth chapter and sixth verse; the fifty-third chapter of the same book; the fifth chapter of Micah, second verse; and many other passages of the Old Testament. In these we find plain predictions which were verified in the birth, ministry and crucifixion of the Savior, which were read by the Jews but not understood by them, because the light of revelation from God was not the source of their information. This was rather the wisdom of their own learning, which led them to reject the Messiah and discard the great message of life which He brought unto them. As there were many plain prophecies relating to the first coming of the Savior and the great work associated with His advent, so there are pointed predictions referring to His second coming and a work of great magnitude to precede that great event. I will call attention to a few as proof that more revelation will be given, and that without it these prophecies could never be fulfilled: "Behold, I will send my messenger, and he shall prepare the way before me; and the Lord, whom ye seek, shall suddenly come to His temple, even the Messenger of the covenant, whom ye delight in; behold, He shall come, saith the Lord of hosts. But who may abide the day of His coming? and who shall stand when He appeareth? for He is like a refiners' fire, and like fuller's sore. * * * And He shall purify the sons of Levi," etc. (Mal. iii:1-3.) This prophecy must refer to His second coming. At His first advent He did not come suddenly; He did not come to His temple. The house of the Lord had become "a den of thieves." He did not accept it. He did not purify the sons of Levi. It was a day when they could in their wickedness abide His coming. "Who shall stand when He appeareth" is clearly a condition when He shall come in power and glory to take vengeance on the ungodly.
