My first response is - any verse I am preaching on. After spending days and hours pondering the readings for any given Sunday and working the text like I'm kneading breading, until it has shape and form and is pliable, I end up loving that text. In the process the text has likewise given shape and form to my life and faith. This is particularly true for those texts that I really struggle with, or those challenging occassions when preaching seems an impossible task and yet words come....

Matthew 22 - when the pharisee asks Jesus to list the one commandment that is the greatest:
"When the Pharisees heard that he had silenced the Sadducees, they gathered together, 35and one of them, a lawyer, asked him a question to test him. 36“Teacher, which commandment in the law is the greatest?” 37He said to him, “’You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ 38This is the greatest and first commandment. 39And a second is like it: ‘You shall love your neighbor as yourself.’ 40On these two commandments hang all the law and the prophets.”the story of Jacob wrestling with the angel in Genesis 32
