Question: In the parable of Matthew 25:14-30, why was the unprofitable servant cast into Hell? This seems to contradict Ephesians 2:8,9; that we saved from Hell, by grace through faith, without good works?
Answer: The Greek for "parable" is "parabola" and means "to lay along side of." It is given to illustrate a spiritual truth. In this parable, the unprofitable servant was a counterfeit Christian; just as Judas, who pretended to be a Christian; but was an impostor.
This is illustrated in the "Parable of the Sower" in Matthew 13:24-39. Good seed was sown; i.e. the Word of God, pictured in the wheat. Satan sowed his seed, the tares, which pictures the lost. (Verses 37-40).
Practically, in the local church there may be those who pretend to be Christians, but are not. Only the Lord knows as in 1 Samuel 16:7 we are told
"...for man looketh on the outside appearance, BUT the LORD looketh upon the heart."
People may fool people, but never the Lord. Therefore, Christ said in Matthew 13:30,
"Let both grow together until the harvest: and in the time of harvest (judgment) I will say to the reapers, Gather ye together first the tares (lost) and bind them in bundles to burn them (Hell): but gather the wheat (saved) into my barn (Kingdom)."
We may be fooled by people, but never by the Lord when He says,
"He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life: but the wrath of God abideth on him." (John 3:36)
