Charles H. Spurgeon on Psalms 48:11

Let mount Zion rejoice. As the first of the cities of Judah, and the main object of the enemies' attack, let her lead the song. Let the daughters of Judah be glad, let the smaller towns join the chorus, for they join in the common victory. Let the women, who fare worst in the havoc of war, be among the gladdest of the glad, now that the spoilers have fled. All the church, and each individual member, should rejoice in the Lord, and magnify his name. Because of thy judgments. The righteous acts of the Lord are legitimate subjects for joyful praise. However it may appear on earth, yet in heaven the eternal ruin of the wicked will be the theme of adoring song. Re 19:1,3: "Alleluia; salvation, and glory, and honour, and power, unto the Lord our God. For true and righteous are his judgments; for he hath judged the great whore which did corrupt the earth with her fornication, and hath avenged the blood of his servants at her hand. And again they said, Alleluia, and her smoke rose up for ever and ever." Justice which to our poor optics now seems severe, will then be perceived to be perfectly consistent with God's name of love, and to be one of the brightest jewels of his crown.
