To do God's will in our work, rest, play and worship.
All our play, work and worship will be characterised by rest, because we will have entered into our Rest, the Rest that Christ entered on His resurrection morning and which is anticipated by the weekly Christian Sabbath/Lord's Day.
All our work, rest and play will be characterised by worship in a way that it is not at present, because we will be free of sin.
It will be a new order which is typologically anticipated on Earth by the perfectly-numbered Seven Day Week, six days of which are for work, rest, play and worship, and one day of which is for rest and worship.
