Once again the modern translations have some funny ideas about the evil eye. The ESV calls it ‘the man who is stingy’; it is hard to imagine how they arrived at that translation.
Christians are people who are interested in the other person and spiritual values, not just things. They see other human beings as having an eternal soul and not just as possessors of material goods which they also covet. This way of looking at people sees that the soul of the other person is of far greater value than anything that we might get from them in this life. It therefore becomes an overriding concern to help the other spiritually and to bring the gospel to them. We cannot do this and at the same time have an eye – an evil eye – to their possessions so that we want the same for ourselves. If we truly love the other, we want them to get free from the sin that we know will bring them into judgment. How then can we imitate them and go after the same earthly things ourselves? How will we have any authority to warn them to leave behind such sins when we do the same things ourselves? To have the gospel uppermost in our hearts and out feet shod with the preparation of the gospel, will be an antidote to this wrong way of looking at others. It will both help them and keep us from falling into the same evil.
