After reading Sam Waldron's defense of the Regulative Principle in Going Beyond the Five Points, some confusion has ensued. I've heard or seen people define worship in such a way as to distinguish between Specific and General Worship. Specific being solely Corporate Worship and General Worship being framed in a Romans 12:1 or 1 Corinthians 10:31 sort of way where all of life is "worship" in the sense that all of life flows from a life of faith and love toward the Lord. My question that then arises is on the Sabbath, when the day is set apart for the public, family, and individual worship of the church, what keeps the private exercises of worship from being anything that the believer finds "worshipful" whether thats playing sports or watching T.V.? Is it solely the command of Isaiah 58 that regulates that our private and family "worship" is to be God-centered activities such as fellowship with believers, Scripture and other theological reading, singing, praying and so on and not other acts of this "general" worship?
