What is the Significance of Abraham and YHWH Being Switched in Genesis 18:22?

I told Cheryl that the Bible is illustration for our development into the true manifestation of God. Bullinger notes in The Companion Bible that Genesis 18:22 was emended from "YHWH stood yet before the Abraham," to "Abraham stood yet before YHWH." My question to Cheryl is: do you see the different impact this alteration makes upon our lives? It was not Abraham stopping YHWH, as we have in our text, it was YHWH stopping Abraham. God hadn't just dropped in for lunch on the way to destroy the low-lifes by the Dead Sea. He had made Abram the Merciful or the Gracious Father. "Hey, Father of Grace, I have just sent two of my best to fry those despiteful users of men in the valley. Whatcha going to do about it?" As the Merciful Father, Abraham had a hard time coming up with an alternate plan. No "Father forgive them, for they know not what they do." He didn't even try for five.

YHWH stands directly before us, saying, "I am bringing a world of hurt to the low-lifes in this world. Whatcha going to do about it?" Let's see, what's our role here?
