God is the Master and Governor of your families–therefore, as such, they should serve Him in praying to Him. If He be your Owner, He is your Ruler too: and doth He not give you laws to walk by and obey, not only as you are particular persons, but as you are a combined society? (Eph. 5:25-33; 6:1-10; Col. 3:19-25; 4:1). Is God, then, the Master of your family, and should not then your family serve Him? Do not subjects owe obedience to their governors? “A son honoureth his father, and a servant his master: if then I be a father, where is mine honour? and if I be a master, where is my fear?” (Mal. 1:6). Where, indeed? Not in prayerless, ungodly families.
—Thomas Doolittle (CL)
