There is nothing more offensive to God than this narrow, self-caring spirit. He cannot work with any who manifest these attributes. They are insensible to the working of His Spirit. (COL 400.1) MC VC

The Jews had been first called into the Lord’s vineyard, and because of this they were proud and self-righteous. Their long years of service they regarded as entitling them to receive a larger reward than others. Nothing was more exasperating to them than an intimation that the Gentiles were to be admitted to equal privileges with themselves in the things of God. (COL 400.2) MC VC

Christ warned the disciples who had been first called to follow Him, lest the same evil should be cherished among them. He saw that the weakness, the curse of the church, would be a spirit of self-righteousness. Men would think they could do something toward earning a place in the kingdom of heaven. They would imagine that when they had made certain advancement, the Lord would come in to help them. Thus there would be an abundance of self and little of Jesus. Many who had made a little advancement would be puffed up and think themselves superior to others. They would be eager for flattery, jealous if not thought most important. Against this danger Christ seeks to guard His disciples. (COL 400.3) MC VC
