No fruit means a bad tree too
A fruitless tree in a useless tree - Matthew 3:10, Matthew 13:22, Luke 13:6-9, Luke 19:11-27, John 15:2, 6, Hebrews 6:8
Jesus warned the Pharisees the kingdom of God would be taken away from people who will not produce - Matthew 21:43
In the Christian life there is no neutrality of example
Either we bear good fruit OR not bearing fruit which shows the condition of our heart - sterile and barren
Bearing no fruit = faithless Christianity
Every tree that does not bear good fruit is cut down and thrown into the fire - Matthew 7:19
