And it shall come to pass in the last days, that the mountain of the LORD’S house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it. – Isaiah 2:2

Of old, the Church was like Mount Zion, a very little hill. What saw the nations of the earth when they looked upon it?-a humble man with twelve disciples. But that little hill grew, and some thousands were baptized in the name of Christ; it grew again and became mighty. The stone cut out of the mountain without hands began to break in pieces kingdoms, and now at this day the hill of Zion stands a lofty hill. But still, compared with the colossal systems of idolatry, she is but small. The Hindoo and the Chinese turn to our religion, and say, “It is an infant of yesterday; ours is the religion of ages.” The Easterns compare Christianity to some miasma that creeps along the fenny lowlands, but their systems they imagine to be like the Alps, outsoaring the heavens in height. Ah, but we reply to this, “Your mountain crumbles and your hill dissolves, but our hill of Zion has been growing, and strange to say, it has life within its bowels, and grow on it shall, grow on it must, till all the systems of idolatry shall become less than nothing before it, till false gods being cast down, mighty systems of idolatry being overthrown, this mountain shall rise above them all, and on, and on, and on, shall this Christian religion grow, until converting into its mass all the deluded followers of the heresies and idolatries of man, the hill shall reach to heaven, and God in Christ shall be all in all.” Such is the destiny of our Church, she is to be an all-conquering Church, rising above every competitor.

O Lord Jesus! by Thy grace turn every one of us to Thyself! Bring in Thine elect; let Thy redeemed rejoice in Thee; and then let the fullness of the nations flow unto Thee, and Thine shall be the glory, for ever and ever. ~ C.H. Spurgeon
