God has no fingers

Today's first reading is from Genesis 18:16-33, where Abraham bargained with God so God won't destroy Sodom and Gomorrah if He finds some righteous people there. The bargain went from fifty to ten. When he arrived at ten, Abraham stopped, probably thinking that it would be too much of a stretch to expect God to agree to a number lower than ten.
In a take on this story, one author re-wrote the story with a twist in the ending: As Abraham was leaving, he failed to see that God did not have hands...
I was struck by this second ending. If Abraham looked closely, he would have seen that God does not have hands. He would have realized that without hands, God cannot count whether there are ten righteous people among the peoples of Sodom and Gomorrah.
This is the God I believe in, a God of infinite mercy and goodness. This is the God that Jesus introduced to us, a God that forgives seven times seven; meaning, without limits.
Our God doesn't keep an account book.
We often take for granted the power of supplication, of praying for others. Since God is a God of mercy and compassion, He is happy when we partake of His mercy and compassion.
In the end, perhaps the bargaining is not really with God but with ourselves. Can I lower my "boundaries" from fifty to zero, and be able to forgive with all my heart? Can I widen my heart so as to give space even to people who do not "deserve" it?
