And if the talent does not represent some gift or some grace given to the servant, then what is it that was given to him? Something was given and something was taken away when it was not used. What was that?
The term "Servant" doesn't have to denote a "Christian" anymore than the parable of the "unrighteous" judge refers to God as being unrighteous. Parables are simply stories to illustrate points.
And if the talent does not represent some gift or some grace given to the servant, then what is it that was given to him? Something was given and something was taken away when it was not used. What was that?
Everything we have, whether we are slaves to sin or slaves to righteousness our gifts and abilities comes from God. If you would like a Biblical example of God taking away something for abusing it I would call your attention to the book of Daniel.
"Yet you, his son, Belshazzar, have not humbled your heart, even though you knew all this, but you have exalted yourself against the Lord of heaven; and they have brought the vessels of His house before you, and you and your nobles, your wives and your concubines have been drinking wine from them; and you have praised the gods of silver and gold, of bronze, iron, wood and stone, which do not see, hear or understand. But the God in whose hand are your life-breath and all your ways, you have not glorified. Then the hand was sent from Him and this inscription was written out."
Now this is the inscription that was written out: 'MENE, MENE, TEKEL, UPHARSIN.' This is the interpretation of the message: 'MENE'--God has numbered your kingdom and put an end to it. 'TEKEL'--you have been weighed on the scales and found deficient. 'PERES'--your kingdom has been divided and given over to the Medes and Persians."
Then Belshazzar gave orders, and they clothed Daniel with purple and put a necklace of gold around his neck, and issued a proclamation concerning him that he now had authority as the third ruler in the kingdom. That same night Belshazzar the Chaldean king was slain.
