Holy Refreshment in God Alone

Pastor walks his children through Westminster Shorter Catechism question 60—especially explaining how Sabbath refreshment via worship is different in kind from the most pious refreshment one can have in anything but worship.

Q60. How is the sabbath to be sanctified? The sabbath is to be sanctified by a holy resting all that day, even from such worldly employments and recreations as are lawful on other days; and spending the whole time in the public and private exercises of God's worship, except so much as is to be taken up in the works of necessity and mercy.
