We were created to work...It is not something that comes in just because of sin. There was work in the Garden of Eden. Adam had to work. He tilled the ground. He grew vegetables. He had to superintend the garden. We know nothing about what it is like to work without pain, without sorrow, without thorns and thistles, and without frustration and weeds. Work is part of creation. It is part of the new creation. There will be work in heaven to do. They will serve him night and day, the book of Revelation says in the closing chapter. There is work to do in heaven—glorious work, fulfilling work, exalting work.1

8 Now in the second year after their coming to the house of God at Jerusalem, in the second month, Zerubbabel the son of Shealtiel and Jeshua the son of Jozadak made a beginning, together with the rest of their kinsmen, the priests and the Levites and all who had come to Jerusalem from the captivity. They appointed the Levites, from twenty years old and upward, to supervise the work of the house of the LORD.
