Isaiah 25:9 (ESV) … “It will be said on that day, “Behold, this is our God; we have waited for him, that he might save us. This is the Lord; we have waited for him; let us be glad and rejoice in his salvation.”
Here is a song of thanksgiving at the fall of Babylon. When she fell, a sigh of relief passed over the whole world, and strong, terrible nations over which she had exerted her tyranny gratefully recognized the goodness and righteousness of Jehovah. We may anticipate, as we read these glowing words, what that song will be when the spiritual Babylon is overthrown, Rev. 19:1–7.
Notice how God suits himself to our need, whether for strength, or refuge, or shadow. Take from him what you are needing most. As the cloud draws its veil over the burning sunshine to mitigate its heat, so does God interpose to reduce the sufferings of his own. The branch, that is, the exulting song of the terrible ones, their song of triumph, shall be hushed. From v. 6 we learn that the hunger of man for God can only be satisfied in Jesus; and from v. 7, that the dread of death and the hereafter, which has lain heavily on humanity as a pall shall be forever ended, when Jesus comes the second time unto salvation. Compare 1 Cor. 15:54. God will not only wipe tears from our eyes, but the fountains of tears shall be dried up, Rev. 21:4.
