Then the
Lord rained upon Sodom and upon Gomorrah brimstone and fire from the
Lord out of heaven; (KJV)
In this passage we have the LORD, YHWH, on Earth Calling down fire and brimstone for the LORD, YHWH, in Heaven. We have two YHWY's in this passage. One of them can be seen. According to John no one has ever seen YHWh. Paul said YHWY can't be seen. He's invisible. That begs the question how did YHWH appear to Abraham and how did Abraham see Him? The only way we can explain this is that Abraham saw YHWH's messenger who uses YHWH's name. The Apostle John said no one Has ever seen God, he even adds, 'at any time.' He said the Son has made Him known. So, God’s Son made YHWH known to Abraham. Thus John is telling us that Jesus God's Son is the one who has made YHWH known to mankind.
The Jews should have known this. Its right there in Exodus that God's messenger would have God's authority because wears His Name and He was speaking for God. In John 8 the Jews wanted to stone Jesus because they said He made Himself equal with God. He was speaking for God so His words were the words of God. They obviously missed the fact that they were talking to their Messiah.
