Revelation 16:7

Others also, either members of the church triumphant or militant, or both, shall in that day give glory to God, as a God of power, able to do such things; of righteousness, thus giving these bloody men their due; and of truth, thus fulfilling both his promises to his people and his threatenings against his enemies. But it is easier to determine who shall thus rejoice, than the time when this joy shall be. This certainly is God's work, but in fieri, now doing, but not yet done.
