Amos says that another change will be in a person's relationships with people. In the church, we call this "fellowship." The untransformed attitude toward people to use people to promote personal interests. People are objects to be used by the unconverted.
Consider Christ's words in Luke 22:24-27:
Now there was also a dispute among them, as to which of them should be considered the greatest. And He said to them, "The kings of the Gentiles exercise lordship over them, and those who exercise authority over them are called 'benefactors.' But not so among you; on the contrary, he who is greatest among you, let him be as the younger, and he who governs as he who serves. For who is greater, he who sits at the table, or he who serves? Is it not he who sits at the table? Yet I am among you as the One who serves." (Our emphasis.)
We have a strong tendency to apply these verses only to those in authority, but it applies to everybody, regardless of status. The carnal-minded take advantage of every opportunity to promote themselves and their interests. The carnal will lie, scheme, steal, twist the truth, deceive, slander, dishonor their parents, and even murder to get their own way, to come out on top, to win, to look good, to get acclaim, or to get rich.
We have clichés like, "Winning is the only thing" or "If you've got it, flaunt it." Those are extremes, but the carnal mind thinks in that direction and attitude. The unconverted use people and situations for their advantage.
A converted person, one whom God is transforming, will not do that. He will put himself, humbly and willingly as Christ did, in the position of a servant. He will not misuse others. At times, he will allow himself to be used—evidence of his transformation into the image of Christ—to make a proper witness for God.
The attitude we see out in the world is especially important to those of us reared under the pervasive influence of American capitalism. Its attitude of intense competition is the driver, the motivation, behind almost everything going on in this country. So, what we witness out in public is an excess of virtually everything except genuine love for one another. It is a major reason divorce is so prevalent today. Vanity and pride are driving husband and wife to compete rather than cooperate.
Truly, coming into contact with God is a humbling experience because now we can start to see ourselves as we should. What happens then is transformation, and true fellowship begins when we seek Him.
Jesus brought this up for at least three reasons: One, to show what God is like in His attitude toward His creation. Two, to show us what we should try to emulate. Three, to help us see evidence of conversion in ourselves.
