In the book Give Praise to God, J. Ligon Duncan III and Terry L. Johnson write, "If your children are in your home for eighteen years, you have 5,630 occasions (figuring a six-day week) for family worship. If you learn a new psalm or hymn each month, they will be exposed to 216 in those eighteen years. If you read a chapter a day, you will complete the Bible four-and-a-half times in eighteen years . . . When you establish your priorities, think of the cumulative effect of this upon your children. Think of the cumulative effect of this upon you, after forty or sixty or eighty years of daily family worship - all this without having to drive anywhere."
