For their duty was to assist the sons of Aaron for the service of the house of the LORD, having the care of the courts and the chambers, the cleansing of all that is holy, and any work for the service of the house of God.
1 Chronicles 23:28
David's passion for the worship of the Lord combined with a gift of administration to organize the Levites around the duties of the house of the Lord in Jerusalem. Not only did David want to make sure that all the preparations were made for a physical temple, but he also wanted to put together the organization of the levitical duties in such a way that when the temple was complete and as worship was conducted in Jerusalem, the Law would be followed and the duties of the priests and Levites could function smoothly for the glory of God.
So by royal edict, the Levites were mustered, arranged, and a duties list was organized. This account is almost purely administrative in its detail. But it is clear that the focus of this was to bring the kind of quality worship that God deserved in His place of meeting. And roles and responsibilities emerged that were clearly understood. By the time David's edict was finished, the transition to worship on the site of the temple was complete. Worship commenced and continued even as Solomon began the work of building a temple there.
An application to consider is the role of administration within God's kingdom. It is a service gift within the church. And there are always details to manage in ministry. The important distinction is that administration as it relates to God's kingdom is not solely about project management. It is much more about the glory of God being emphasized by offering our organizational gifts and abilities to Him.
I am so thankful that God uses us in this way. And many people labor with servant's hearts behind the scenes so that God's glory may be known among the nations. Some of us organize and others of us perform the tasks assigned. But all of us worship God in His work for His purpose so that His name may be great among all people.
