WCF 21.6 Neither prayer, nor any other part of religious worship, is now, under the gospel, either tied unto, or made more acceptable by any place in which it is performed, or towards which it is directed: but God is to be worshiped everywhere, in spirit and truth; as, in private families daily, and in secret, each one by himself; so, more solemnly in the public assemblies, which are not carelessly or willfully to be neglected, or forsaken, when God, by his Word or providence, calleth thereunto.
We all realize the silliness of the attitude "I'm just not a good Christian because I didn't do my 'quiet time' today"...or the self-righteous attitude of thinking you're a good Christian because you can check the 'quiet time' box off your to-do list for the day.
Obviously, that attitude is silly and wrong, but wouldn't the other extreme be wrong of not considering private and family worship to be some of the duties of a Christian?
When the Puritans and others refer to private and family worship as "duties," what exactly do they mean by that word? Common sense says, "Yes, we need to spend time in worship of God each day," but how do we derive this understanding of these being "duties" from Scripture?
This is somewhat of a new thought for me, so some explanation and thoughts would be helpful.
