"Then the men turned away from there and went toward Sodom, while Abraham was still standing before the LORD. Abraham came near and said, 'Will You indeed sweep away the righteous with the wicked?'"
Genesis 18:22:23
Here we find Abraham's great intercessory prayer on behalf of Lot and his family. He didn't go down to Sodom and try to save them himself, He asked God to do it. Compassion drove Abraham to ask God for his loved ones' salvation. God listened to and granted Abraham's request. The Lord is still hearing and answering intercessory prayer for the unsaved today. It is our job to pray. It is God's job to save.
