Yes, I know that we live in the New Covenant era. I know that there is no longer a temple built by human hands. I know there are no longer any appointed feasts for the people of God.
But I also know that Hebrews admonishes us to keep in the habit of meeting together, and if we are wise we will make a special effort to meet together on the days that aren't as convenient: when church meetings and services fall on holidays and long weekends. Where I live, I know of families who "take the summer off" from churchgoing, either because their schedules are already filled, or they have a cabin elsewhere. Let's simply observe a logistical fact: this type of lifestyle isn't conducive to being built up together into the body of Christ (I'm also aware that I might well be tempted to disappear into the woods or to the island or into the California desert if I could afford to).
So I'm making a special effort to join with the people of God for worship on New Year's Day. It probably won't feel much different than a usual Sunday at my church, but that's not the point, is it? The thing about a God-glorifying habit is that it's just another step along the road of everyday Christianity.
Don't feel condemned if you are attending a party tonight instead of a service tomorrow. Condemnation and guilt indicate another problem altogether, beyond the scope of this brief blog entry.
But as for me and my house, we're with Erik.
