In this sublime transaction we have all the scenes and circumstances of a mighty revival of true religion. It is a vast camp-meeting, in which God himself is the preacher, speaking in men’s ears with an audible voice from the top of Sinai, and alternately proclaiming the law of righteousness and the gospel of grace, calling Israel from their idolatries and sins to return unto him, and offering himself as not only the God of their fathers, but their own Deliverer already from the Egyptian bondage, and ready to be their God and portion—to give them at once the earthly Canaan, and to make it a pledge of their ultimate endowment with the heavenly. The people had professed with one accord to turn to God, and pledged themselves, emphatically and repeatedly, to take him as their God, to walk in his statutes and do his will, to be his people. It is true that, to many, the gospel then preached was of no profit, for lack of faith; whose carcasses therefore fell in the wilderness. (Heb. iii, 17-19; iv, 2.) But it is equally true that the vast majority of the assembly at Sinai were children and generous youth, who had not yet been besotted by the Egyptian bondage. To them that day, which was known in their after history as “the day of the assembly” (Deut. x, 4; xviii, 16), was the beginning of days. Its sublime scenes became in them the spring of a living faith. With honest hearts they laid hold of the covenant, and took the God of the patriarchs for their God. Soon after, the promise of Canaan, forfeited by their rebellious fathers, was transferred to them. (Num. xiv, 28-34.) Trained and disciplined by the forty years’ wandering, it was they who became, through faith, the irresistible host of God, the heroic conquerors and possessors of the land of promise. Centuries afterward, God testified of them that they pleased him: “I remember thee, the kindness of thy youth, the love of thine espousals, when thou wentest after me in the wilderness, in a land that was not sown. Israel was holiness to the Lord, and the firstfruits of his increase.”—Jer. ii, 2, 3. Until the day of Pentecost, no day so memorable, no work of grace so mighty, is recorded in the history of God’s dealings with men as that of the assembly at Sinai.
