It's easy to see the connection between judging and truth. In a court of law, the whole purpose of the judge is to find the truth. Any time anyone judges anything, we hope it is on the basis of the truth. It's no wonder, then, that judging and judgment in the Bible represent truth being put to work. Depending on the circumstances judging can be teaching truth, determining someone's character from truth or setting order to things according to truth. There is a twist, though -- when the Lord is referred to as a judge, it actually signifies Divine Good, rather than Divine Truth. This is because the Lord judges us ultimately from love, and his truth flows from that love.
Rain
'To rain' signifies influx. In Genesis 2:5-6, Exodus 34:25-27, and Hosea 6:3, 'rain' signifies the tranquility of peace when the combat of temptation ceases. 'An inundating rain' signifies the vastation of truth, as in Ezekiel 3:11-14. 38:23, and temptation, as in Matthew 7:24-27. In Genesis 7:4, 'rain' signifies temptation and vastation. 'Rain,' in a positive sense, denotes blessing, but in the opposite sense, damnation

2443. Verse 24 And Jehovah rained on Sodom and on Gomorrah brimstone and fire from Jehovah out of heaven.
'Jehovah rained on Sodom and on Gomorrah brimstone and fire' means the hell of those governed by the evils of self-love, and by falsities deriving from these - 'raining on' meaning to be condemned, 'brimstone' the hell of the evils of self-love, 'fire' the hell of falsities deriving from these. 'From Jehovah out of heaven' means from the laws of order in regard to truth, because they separate themselves from good.
