Luke has just finished writing about the parables of the Lord, where he has pressed the point that genuine faith is evident faith (v1-21). If there is no fruit on the branch then there is no faith in the root. Faith that begins is faith that preserves – “faith without works is dead” (Js. 2:20). A person that is saved can never be lost but it is equally true that a person who is saved will overcome; “for whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.” (1 Jn. 5:4).
