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

Is it not a great subject for praise that the nations of the earth may flow to the hill of God and to His House? If I were to tell you that all the nations of Europe were climbing the sides of the Alps, you would ask me, “And what benefit do they gain thereby? They must pass over the slippery fields of ice and they may lose their lives in the midst of the bottomless chasms that are overhung by the mighty precipices; they may suddenly be overwhelmed and buried in the all-destroying avalanche, and should they reach the summit they must fall down exhausted. What is there that men should covet in those barren heights; rarefied air and cold would soon destroy them, should they attempt to exist there.” Ah, but it is not so with God’s hill. There shall be no snow upon its summit, but the warmth and light of Jehovah’s love, there shall be no chasms in its side wherein souls may be destroyed, for there shall be a way, and a highway, (the unclean shall not pass over it) a way so easy that the wayfaring man shall not err therein.

Ye are come to a mountain which is not forbidden to you. there are no bounds set about it to keep you off, but you are freely bidden and freely invited to come to it. Oh! ye people that today hear the words of Jesus! ye are now this day invited to come to the mountain of His Church, on which stands His cross and His throne. ~ C.H. Spurgeon
