Genesis 18:23-32 -- Abraham Intercedes
“If they [lost sinners] will not hear you speak, they cannot prevent your praying. Do they jest at your exhortations? They cannot disturb you at your prayers. Are they far away so that you cannot reach them? Your prayers can reach them. Have they declared that they will never listen to you again, nor see your face? Never mind, God has a voice which they must hear. Speak to Him, and He will make them feel. Though they now treat you despitefully, rendering evil for your good, follow them with your prayers. Never let them perish for lack of your supplications” (Metropolitan Pulpit, vol. 18, pp. 263–264).
