It would be difficult, if not impossible, for the genuine believer to do something in the name of the Lord and to His glory without worshipping. The expression indicates a return to the old Law of Moses, a ritualistic system that was superseded by Jesus and the New Way. There were no material structures to build and maintain, and no ecclesiastical pulpiteers to support. Money was collected only when a need arose. In today's scene, a collection plate is passed around about every time we cross our legs.
Believers are free to support any good cause at any time, in or out of the corporate assembly.
Ninety-nine percent of my giving goes to needy causes that are not even related to the group whose assemblies I attend. The greatest man who ever walked upon this earth lost His life at the hands of the professional clergy. It would be no different if Jesus were to return to earth in the flesh today. Man's opposition to reform hasn't changed. Today's religious establishment is the enemy of reformers and reformation.
