We are busy people. Congregations can be busy places too. There is always work to do, and always too few people to do it. Sometimes the work piles up so much that it even overshadows worship. That must never be.
Worship always comes first in the Christian congregation.
It's why God gathers a congregation in the first place, so that we can sit at the feet of Jesus and hear His Word. Any work that takes the place of worship, no matter how honorable or important it might otherwise be, is idolatry. When we're so busy we can't pause to hear God's Word, we can hardly turn around and ask God to bless what we're so busy doing. The saying goes that idle hands are the tools of the devil. But busy hands can also be the devil's delight when they keep us from the Word of God.
