For a day in Your courts is better than a thousand. I would rather be a doorkeeper in the house of my God Than dwell in the tents of wickedness. - Psalm 84v10
We live it what is very much a success oriented society. Partly because of that many of us have a desire to do something that seems successful or something that makes us look important. Some jobs are seen as being really important. Doctors, lawyers, executives, and others like that are important people, at least in the eyes of society.
Other jobs are not so 'important' to society in general. One of the jobs that would fit into the ''less desirable' category would be a doorman. Anybody can do that. All you have to be able to do is open the door. It doesn't take a lot if education, skill, or experience to do that. Even a monkey can be trained to open a door.
Of course, in reality, there is no such thing as a bad job. Every job is honourable when it is done well. Our perceptions are based on our success oriented culture.
The psalmist states here that he would rather take the most menial of jobs in the Lord's house that to live amongst the wicked. He knew that any work done for God is more important than any job for the world because of the eternal consequences.
Sure, it is possible to be a success in the eyes of the world and serve the Lord. That is not the issue. The issue is that we seek to serve God, no matter what our task in doing it.
