The psalmist proclaims: “Behold, how good and how pleasant it is for brethren to dwell together in unity!” Unlike the unity of unbelievers and the heathen, the Lord rejoices in the righteous unity of His people. King David was someone who knew and experienced the difficulties of division. He spent a great deal of his life running from a king and those who were against him. Even in the beginning of his reign, the people were divided (2 Samuel 2:8-11). It was not until 7 1/2 years later that the people were united in David (2 Samuel 5:1-5). When the people dwelt in unity, David rejoiced. He likened it to the source of spiritual life for the nation of Israel, the priesthood (Psalm 133:2), and to the source of physical life in the dew of Hermon (Psalm 133:3). In other words, the right kind of unity gave life and hope to the nation!
It is easy to tell others what to do and how to do it, but very unwise to fail to follow one’s own instructions and teachings. In fact, man naturally seems to want to place greater burdens upon others than he himself is willing to bear. This was one of the primary issues addressed by those attending the council of Acts chapter 15 in Jerusalem. Peter concluded with the other apostles in agreement that it was not right to ask others to bear a yoke that previous generations were unable to bear (Acts 15:10). This does not mean that believers change their teaching to fit their obedience. Rather, believers ought to obey the truth and teach these truths to others. How many preachers and teachers have spoken about subject matters only to refuse to obey the very truths they have taught to others?
