21 I will go down and see whether they have done according to the cry that is come to me: or whether it be not so, that I may know. 22 And they turned themselves from thence, and went their way to Sodom: but Abraham as yet stood before the Lord. 23 And drawing nigh he said: Wilt thou destroy the just with the wicked? 24 If there be fifty just men in the city, shall they perish withal? and wilt thou not spare that place for the sake of the fifty just, if they be therein? 25 Far be it from thee to do this thing, and to slay the just with the wicked, and for the just to be in like case as the wicked, this is not beseeming thee: thou who judgest all the earth, wilt not make this judgment.
21 "I will go down"... The Lord here accommodates his discourse to the way of speaking and acting amongst men; for he knoweth all things, and needeth not to go anywhere for information. Note here, that two of the three angels went away immediately for Sodom; whilst the third, who represented the Lord, remained with Abraham.
26 And the Lord said to him: If I find in Sodom fifty just within the city, I will spare the whole place for their sake. 27 And Abraham answered, and said: Seeing I have once begun, I will speak to my Lord, whereas I am dust and ashes. 28 What if there be five less than fifty just persons? wilt thou for five and forty destroy the whole city? And he said: I will not destroy it, if I find five and forty. 29 And again he said to him: But if forty be found there, what wilt thou do? He said: I will not destroy it for the sake of forty. 30 Lord, saith he, be not angry, I beseech thee, if I speak: What if thirty shall be found there? He answered: I will not do it, if I find thirty there.
Don't we plead on behalf of others when we know they sin greatly. Don't we do as Abraham had done, ask to save though there might be none who would would be found. Our prayers and pleadings for those who have gone astray many times are answered and God's divine hand reaches out and touches us. The request to save is in our hearts for those who have fallen away and chose to live life away from God. A life of wickedness that speaks for itself. When goodness has long fled the morals of mankind. Would we be able to plead for cities that are ripe in wickedness or as Abraham plead to save if only one were found with faith and goodness in it. Isn't that what we are called to do, pray for others. Pray for their conversion so their fate doesn't end up in the fiery furnace of the nether world. And what about us, don't our consciences speak to us of living according to God's Will and abiding in his law. Who are we then if our judgement goes as the way of Sodom, if we refuse to heed or listen to our interior conscience to do right. If we did that then our prayers would have all come to fruition and humanity would find peace.
