The last of the three servants behaved very differently when faced with the same situation. What the other two servants regarded as a privilege he regarded as a burden.
God send the gospel into the world, and causes his light to shine in the darkness. Although he certainly knows how hard the hearts of men are, and how stubborn and rebellious men and women are, so that they will never turn to Christ of their own free will, yet the reasonableness of what God does exposes human unreasonableness. The parable represents God by a benevolent master who magnanimously sets up a wonderful opportunity for his lowly servants. God expects that we, who hear of a way of salvation, of free forgiveness from all our sins and peace with God forever, should respond with amazement at the goodness and mercy of God and embrace that goodness with all our hearts. The fact that it is otherwise does not surprise the Lord, but it demonstrates our wickedness and it grieves his heart.
As rebels against God we take his truth and we bury it in the ground putting it out of use. We are in possession of the most precious article that we could have access to in this world and yet we do nothing with it. Don’t men and women realise the potential of the gospel to give them life? Why don’t they respond? The explanation is given a few verses later. It has to do with the servant’s perception of his master.
