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…
Observe the figure. It does not say they shall come to it, but they shall flow unto it.
1. It implies, first, their number. Now it is but the pouring out of water from the bucket; then it shall be as the rolling of the cataract from the hillside.
2. Their spontaneity. They are to come willingly to Christ; not to be driven, not to be pumped up, not to be forced to it, but to be brought up by the Word of the Lord, to pay Him willing homage. Just as the river naturally flows downhill by no other force than that which is its nature, so shall the grace of God be so mightily given to the sons of men, that no acts of parliament, no state churches, no armies will be used to make a forced conversion.
3. But yet again, this represents the power of the work of conversion. They "shall flow to it." Imagine an idiot endeavouring to stop the river Thames. The secularist may rise up and say, "Oh, why be converted to this fanatical religion? Look to the things of time."
( C. H. Spurgeon.)
