And He sat down, called the twelve, and said to them, “If anyone desires to be first, he shall be last of all and servant of all.” Mark 9:35

Strife for the supremacy makes manifest a spirit that, if cherished, will eventually shut out from the kingdom of God those who cherish it. The peace of Christ cannot dwell in the mind and heart of a workman who criticizes and finds fault with another workman simply because the other does not practice the methods he thinks best, or because he feels that he is not appreciated. The Lord never blesses him who criticizes and accuses his brethren, for this is Satan’s work.” {Evangelism 102.3}
