But in the last days it shall come to pass, that the mountain of the house of the LORD shall be established in the top of the mountains, and it shall be exalted above the hills; and people shall flow unto it. – Micah 4:1

The Christian religion has become more conspicuous now than ever it was. In every part of the world all people are thinking of it. The hill is already growing, and mark you, it is to grow higher yet; it is to be so conspicuous, that in every hamlet of the world the name of Christ shall be known and feared. Rising higher, and higher, and higher, from north to south, from east to west, this mountain shall be beheld; not like the star of the north which cannot be seen in the south, nor like the “cross” of the south which must give way before the “bear” of the north-this mountain, strange to say it, contrary to nature shall be visible from every land. Far-off islands of the sea shall behold it, and they that are near shall worship at the foot thereof. It shall be pre-eminently conspicuous in clear, cloudless radiance gladdening the people of the earth. This I think is one meaning of the text, when the prophet declares “that the mountain of the Lord’s house shall be established in the top of the mountains. and shall be exalted above the hills.” There is something awfully grand in a mountain, but how much more so in such a mountain as is described in our text, which is to be exalted above all hills, and above all the highest mountains of the earth.

The Church is to be awful in her grandeur. Ah! now she is despised; the infidel barketh at her, it is all he can do; the followers of old superstitions as yet pay her but little veneration. Ay, but the day shall come when men shall bow before the name of Christ, when the cross shall command universal homage…The hour cometh, yea, and now draweth nigh, when the mountain of the Lord’s house in her awful grandeur shall be established on the top of the mountains. ~ C.H. Spurgeon
