The proclamation of "The Kingdom of Heaven" by John the Baptist defined the exact time in the world's history when this Kingdom took its rise. And our Lord afterwards called express attention to this, saying, "The Law and the Prophets were until John: since that time the Kingdom of God is preached, and every man presseth into it[2]" (S. Luke xvi. 16). And because John was only the Herald going before, and was not himself enrolled as a subject of the Kingdom, He added, (after referring to the greatness of John the Baptist), "Notwithstanding, he that is least in the Kingdom of Heaven is greater than he" (S. Matt. xi. 11). Thus we are assured that "The Kingdom of Heaven" began from the proclamation of John the Baptist; and, therefore, we know for certain that the Lord Jesus Christ, whose coming he proclaimed, is the King of this Kingdom. This is the great truth which forms the foundation of all the teaching of the New Testament; and it is of the utmost importance to have a clear idea of it. The Lord Jesus Christ came to be the Saviour of the world by becoming King of a spiritual Kingdom of grace and blessing, whose subjects were to be purchased and redeemed by His own Blood shed upon the Cross. He was not merely the greatest of God-inspired teachers: but He came to found God's Kingdom upon earth, and to rule in love over the hearts of men of all nations and ages, and thus prepare them for life everlasting. And when Nicodemus, one of the rulers of the Jews, thus addressed Him, "We know that thou art a teacher come from God," He at once endeavoured to lead him to grasp this truth, by the abrupt reply, "Verily, verily, I say unto thee, Except a man be born again, he cannot see the Kingdom of God;" and again, "Except a man be born of water and of the Spirit, he cannot enter into the Kingdom of God" (S. John iii. 2-5). In other words, men must not merely listen to His teaching; but they must have their eyes opened to see Him as the promised King, and receive the principle of a new Life as His subjects; or, else, His coming would be in vain. Taking now as our starting-point the great truth that the Lord Jesus Christ came to found a Kingdom, our next enquiry must be respecting the subjects or citizens of this Kingdom. Who are the subjects of "The Kingdom of Heaven?"
