Fruit is often used as a metaphor for a "good." In the New Testament, and specifically in this passage, fruit is associated with a good outcome (Matt. 3:8; 7:16; John 4:36; 15:8; Rom. 1:13; 6:21).
"Good, is just not good enough." That was the headline for the announcement that the Denver Broncos head coach John Fox and Executive Vice President John Elway had come to an agreement that they would part ways. This separation of a winning head coach sent shockwaves throughout the sports world.
