It is important to remember Jesus was a Jew teaching Jews using their scripture. For those Jews, Judgement was an occasion of universal rejoicing not of punishment for your sins.
“The ancient Jews, like ourselves, think of God’s judgement in terms of an earthly court of justice. The difference is that the Christian pictures the case to be tried as a criminal case with himself in the dock; the Jew pictures it as a civil case with himself as the plaintiff. The one hopes for acquittal, or rather for pardon; the other hopes for a resounding triumph with heavy damages. Hence he prays ‘judge my quarrel’, or ‘avenge my cause’ (35:23). And though, as I said a minute ago, Our Lord in the parable of the Sheep and the Goats painted the characteristically Christian picture, in another place He is very characteristically Jewish.” [C.S. Lewis, Reflections on the Psalms]
Gives a whole new meaning to John 3:16 “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.” We have won by the grace of God our civil suit; God’s judgement “is eternal life in Christ Jesus our Lord.” God is LOVE!
