From Fr. Jude Botelho
The first reading introduces us to Abraham as he intercedes with God for the city of Sodom and Gomorrah. What strikes us immediately is the tone of the conversation between Abraham and God. It certainly implies a relationship. Firstly, we see Abraham pleading not for himself but for the needs of others. Secondly, what comes across through the reading is the belief that good people matter and have a tremendous influence on others. Thirdly, we see that Abraham perseveres in his pleading with the Lord. The point of the passage is not that prayer changes God but rather that prayer gives us a share in His power and definitely, that prayer changes us so that we can accept whatever is God's will for us.
