The parable of the vineyard laborers shows the generosity of God and the jealousy of men. Envy or jealousy is a capital sin which is caused by one’s inability to rejoice at the good fortunes of others. The envious person is not happy and even complains about what he perceives to be an injustice to himself – the good fortune of someone else.
In the Book of Job, Job said, “The Lord gives and the Lord takes away. Blessed be the name of the Lord!” We should have this attitude when we receive material blessings from God. We should be thankful to Him while being aware that material things do not last. When another person receives blessings from God, we should rejoice with him and praise God’s generosity. God wants to shower His graces on all men. But to each person God gives something different because He treats us as individuals. So we must not be envious of what other people receive from God. Instead we should mind our own business, do our Christian duties every day with dedication, and not expect anything in return. We must consider ourselves unworthy servants of the living God. Then if we ever do receive something for our efforts, we would be truly grateful, knowing that God is gracious.
