As the name Kingdom Hall implies, the central Bible teaching discussed there focuses on God’s Kingdom​—the theme of Jesus’ ministry.​—Luke 8:1.

They are centers of true worship in the community. From that location, the preaching of the good news of the Kingdom is carried out. (Matthew 24:14) Kingdom Halls vary in size and design, but all are modest structures, many accommodating more than one congregation. In recent years, we have built tens of thousands of new Kingdom Halls (an average of five each day) in order to keep up with the increase in our congregations. How is this possible?​—Matthew 19:26.

They are built with donations made to a central fund. These donations are sent to the branch office so that money can be made available to congregations needing to build or remodel a Kingdom Hall.

They are built by unpaid volunteers from all walks of life. In many lands, Kingdom Hall Construction Groups have been organized. Teams of construction servants and volunteers move from one congregation to the next within a country, even in remote areas, assisting the local congregations with the construction of their Kingdom Halls. In other lands, qualified Witnesses have been appointed to supervise the building and renovating of Kingdom Halls within an assigned region. Although many skilled tradesmen from the region volunteer their labor at every building site, members of the local congregation make up the bulk of the volunteer labor force. Jehovah’s spirit and the whole-souled efforts of his people are making all of this possible.​—Psalm 127:1; Colossians 3:23.

• Why are our places of worship called Kingdom Halls?

• How is it possible to build Kingdom Halls all around the world?

Every Kingdom Hall of Jehovah’s Witnesses bears God’s holy name. Therefore, we feel that sharing in keeping the building clean, presentable, and in good repair is a privilege and an important part of our sacred worship. All can participate.

Volunteer after a meeting to do some cleaning. After each meeting, brothers and sisters happily do a light cleaning to tidy up the Kingdom Hall. Once a week, a more thorough cleaning is done. An elder or a ministerial servant coordinates the work, usually following a checklist of things to do. Depending on the need, individuals volunteer to sweep, mop, or vacuum the floor, do dusting, straighten the chairs, clean and disinfect the bathrooms, wash windows and mirrors, dispose of trash, or do exterior cleaning and care for the yard. At least once a year, a day is set aside to do a major cleaning. By including our children in some duties, we teach them to respect our place of worship.​—Ecclesiastes 5:1.

Lend a hand in making any needed repairs. Every year, a detailed inspection is made of the Kingdom Hall, inside and out. Based on this inspection, regular maintenance work is done to keep the hall in good repair, helping to avoid unnecessary expenses. (2 Chronicles 24:13; 34:10) A clean and well-maintained Kingdom Hall is a worthy place in which to worship our God. By having a share in this work, we show how close Jehovah and our place of worship are to our heart. (Psalm 122:1) This also creates a favorable impression in the community.​—2 Corinthians 6:3.
