Jeff Hendrix on Mark 12:28-31. This is the fourth Sunday of Advent. (Scripture reading at first in Arabic Luke 2:1,3-7 and Afrikaans Luke 2:8–16.) When a teacher of the law asks Jesus what is the greatest commandment, Jesus gives us a model for taking God's love and using it as something that the world really wants to see. Love that shines like a light in a dark place.
