This parable Luke 13 is a serious warning against the danger of not bearing ripe and pure fruit, that is, living without sin on earth.
This parable also reveals the patience of God, who waits for years, giving time for a person to take a radical decision: the decision to live a life of holiness and to bear fruit worthy of radical repentance.
God does not judge hastily. He gives time, He warns, He exhorts, He waits. But His patience has a purpose: that man may abandon sin completely and produce holy fruit. This patience is not permission to remain in sin, but an opportunity to suffer in the flesh, to say no to temptation every day, and to enter a life of victorious sanctification.
As Romans 6:22 clearly states, without holiness—without ripe fruit, without sin no one can have eternal life. Eternal life is the end only for those whose lives produce mature fruit of holiness. There is no salvation without this fruit.
Therefore, every possible effort must be made to suffer in the flesh, to say no daily to temptations, to reject every sinful desire, in order to be saved. This suffering is not useless; it is salvific. As Scripture teaches, he who suffers in the flesh has ceased from sin.
Matthew 3:10 is also clear and can be directly correlated with this passage in Luke:
“Every tree that does not bear good fruit is cut down and thrown into the fire.”
If a tree does not bear fruit of holiness without sin, then there is no salvation for that person. Profession of faith, religious activity, or verbal confession cannot replace the necessity of holy fruit.
A fruitless tree is not a weak Christian; it is a condemned tree. The absence of holy fruit proves the absence of true repentance and true life.
This parable therefore stands as a final call:
either a radical life of holiness without sin,
or judgment.
There is no middle ground.
