Psalms 136:21

The great things God did for Israel, when he brought them out of Egypt, were mercies which endured long to them; and our redemption by Christ, which was typified thereby, endures for ever. It is good to enter into the history of God's favours, and in each to observe, and own, that his mercy endureth for ever. He put them in possession of a good land; it was a figure of the mercy of our Lord Jesus Christ.

And gave their land for an heritage. As Lord of the whole earth he transferred his estate from one tenant to another. The land did not become the property of the Israelites by their own sword and bow, but by a grant from the throne. This was the great end which all along had been aimed at from Egypt to Jordan. He who brought his people out also brought them in. He who had promised the land to the seed of Abraham also saw to it that the deed of gift did not remain a dead letter. Both our temporal and our spiritual estates come to us by royal charter. What God gives us is ours by the best of titles. Inheritance by God's gift is tenure which even Satan cannot dispute. For his mercy endureth for ever. Faithful love endures without end, and secures its own end. "Thou wilt surely bring them in", said the prophet poet; and here we see the deed complete.

Till they reach the promised land

Mercy still the same must stand.
