Mateus 20:15

Is it not lawful for me to do what I will with mine own? or is thine eye evil, because I am good?

Let it be remembered that all have sinned and fallen short of God's glory. This parable shows that men may forget this in two ways: (1) They may forget it like the ones who worked all day and supposed that they were better than the ones who came later; (2) and they may forget it like the eleventh-hour workers would have forgotten it if they had objected to the householder's payment of the "firsters" on the grounds that the "firsters" had the wrong attitude! Although such a development did not occur in the parable, such an objection against the householder is found in the writings of commentators from Origen and Irenaeus to Alford and Trench. Let no man object to God's saving men on any grounds whatsoever: (1) whether from the allegation that some have not worked like "US," or (2) from the allegation that their ATTITUDE makes them inferior to "US," or from whatever premise, real or imaginary, true or false. It is altogether righteous and lawful for God to do what he wills.
