The gatekeepers were assigned to the four directions: the east, west, north, and south. And their brethren in their villages had to come with them from time to time for seven days. For in this trusted office were four chief gatekeepers; they were Levites. And they had charge over the chambers and treasuries of the house of God. And they lodged all around the house of God because they had the responsibility, and they were in charge of opening it every morning. 1 Chronicles 9:24-27

One of the most responsible positions in the ancient Israel society is that of the gatekeeper.
These individuals were stationed at the entrances of city gates, palace gates, or temple gates. Their responsibility was in keeping order in the area they guarded. A gatekeeper lax in his duty could subject the city to an invading army or plague.
Oftentimes, business was conducted at the city gate. (c.f. Gen 19:1, Deut 21:18-21, Ruth 4:1-11, 2 Sam 18:1-5)
A gatekeeper is a trusted office and at this particular time, there are two hundred twelve men on a seven-day rotation.

In the modern church, there is a gatekeeper. You might call that individual a greeter or usher but it is still a trusted position.
This is the first person a visitor sees and interacts within your church.
It is, therefore, an important position.
First impressions of the rest of the service are made when a visitor is greeted by your gatekeeper.
A gatekeeper not only greets visitors and regular attendee’s, but can pass out bulletins or other materials, answer questions about the service, indicate the direction for a drink of water or the restrooms, and give a visitor card.

Please pray and choose well and if God has given you the gift of gatekeeping (not everyone has it) then please tell the pastor or elder of your desire to help in this vital area.
