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!
When someone receives rebuke from another person, it is rarely easy to accept. The person receiving the rebuke may lash out in anger even when the rebuke is scripturally made with longsuffering. The Bible confirms this type of reaction when it says, “They hate him that rebuketh in the gate, and they abhor him that speaketh uprightly” (Amos 5:10). This type of reaction is not one of a wise man, nor is it from one who has taken the time to consider the godly rebuke’s content and intention. The Bible also says that afterwards the one who rebukes finds “more favour than he that flattereth with the tongue.” Ultimately, the Lord’s reaction is what matters and the scriptural practice of rebuking others within the authority of scripture pleases Him.
