Rev. 16
The word judgement has a scary sound. In general, it means to vindicate or hold to a standard. When the person judged has done wrong, it can mean punishment.
In most competitive events, there is a judge or evaluating official . In a baseball game, an official is designated to call balls and strikes. Likewise there are judges to make calls on each base, safe or out. Video replay has helped make some sports judgements more fair.
God is the Great Judge Who sits in the heavens and watches everything. He is the only perfectly accurate Judge of everything. We can have the blood of Jesus cleanse us from all unrighteousness and go on living our lives with the peaceful assurance that He will control the outcome of every judgment we are subjected to. We can thereby live life and REST. Just trust Him.
