We will not neglect the house of out God

Nehemiah 11:1-36
The leaders of the people settled in Jerusalem. The rest of the people cast lots to bring one out of every ten of them to live in Jerusalem, the holy city, while the remaining nice were to satay in their own towns.
These are the provincial leaders who settled in Jerusalem now some Israelites, priests, Levites, temple servants and descendants of Solomon's servants lived in the towns of Judah, each on their own property in the various towns, while other people from both Judah and Benjamin lived in Jerusalem.
There were descendants of Judah, Benjamin, priests,Levites, gatekeepers,..
The people pledge specifically to keep the law's requirements on marriage, the sabbath, and taxes, tithes and offerings to support the Temple services, priests and Levites. 'We will obey all that the Lord out God commands... We will not neglect the house of out God.
A list of those already living in Jerusalem. The number was increased by a 10 per cent levy(征集) on the villages around.
Why?
Jerusalem is a city surrounding a wall, but more important is the Temple, there was the house of the Lord, so they need make a pledge and continue the service in the Temple and many servant of Temple to serve the Lord. More important they have to obey the command of the Lord, then they may serve the Lord.
A servant of the Lord need to a man of God, who obey the commands of the Lord and  do the right things and honor the name of the Lord.
Church is a building, but more important is the people in church should be real Christians before the Lord.
How?
There are people come to church to be servant of the Lord and take care of the House of God.
