Charles Spurgeon Commentary Isaiah 49:13

"Sing, O heavens; and be joyful, O earth; and break forth into singing, O mountains: for Jehovah hath comforted his people, and will have compassion upon his afflicted." — Isaiah 49:13 (ASV)

Sing, O heavens; and be joyful, O earth; and break forth into singing, O mountains: for the Lord hath comforted his people, and will have mercy upon his afflicted.

How? Why, by the very coming of Christ, by his birth at Bethlehem, and all the blessings which come with the Incarnate God, his afflicted ones are consoled, and all his people are divinely comforted. Shall we not, then, rejoice in Christ, who is himself so full of joy that he teaches the very heavens to sing, and the mountains to break forth into praise?

Sing, O heavens; and be joyful, O earth; and break forth into singing, O mountains; for the LORD hath comforted his people, and will have mercy upon his afflicted.

When God blesses his Church, he blesses the world through her.

Hence, heaven and earth are invited to be glad in the gladness of the Church of God.

Oh, that God would visit his church; no, he has already done so, and I feel inclined to cry out, as the text does, Sing, O heavens; and be joyful, O earth: and break forth into singing, O mountains: for the LORD hath comforted his people.
