Faith and allegiance

In Luke 10:25-28 a Jewish legal authority asks Jesus how to inherit eternal life. Jesus asks him what the Law (of Moses) says and the man responds saying that people must Love God with all their heart, soul strength and mind; and their neighbor as themselves. Jesus told him he had answered correctly. But what does this have to do with salvation? Don’t we have to “believe” or have “faith” to be saved? Darrell Bock’s interpretation of this passage hits the nail on the head: “This answer does not defend righteousness by works. Jesus’ approval of the answer in the next verse comes because at its heart the answer is an expression of total allegiance and devotion that in other contexts could be called faith. At the heart of entering the future life is a relationship of devotion, a devotion that places God at the center of one’s spiritual life and responds to others in love” (Bock, Darrell, Luke 9:51-24:53.
