‘Therefore the kingdom of heaven is like a king who wanted to settle accounts with his servants’ (Matthew 18:23)
"In the parable introduced by the above verse, both servants bear the same relation to the king as each other. They are called "fellow servants" (28+29).
"The indulgence shown by the king to the destitute and desperate first servant, had ethical implications for him. He should have incorporated forgiveness into his lifestyle. There is an important organic relationship between the King, the servant, and his fellowservant. When the first servant, having had his entire debt canceled, threw his fellow servant in prison, his action bore jarringly on his relation to the fellow, as well as against his own relation to the king who had been so compassionate."
"The first servant's debt was enormous compared to that of the second servant. I am always the first servant. It is always better for me to think of my own debt to God, as having been greater than anyone else's. By keeping this perspective, mercy will loom large to me, and I will be more likely to forgive my fellow servants."
"In... humility---consider others better than yourselves" (Philippians 2:3).
Words of civility.
It doesn't mean I have to enjoy beating my head against a wall, however.
