C.H. Spurgeon:

I trust there are none here present, who profess to be followers of Christ who do not also practice prayer in their families. We may have no positive commandment for it, but we believe that it is so much in accord with the genius and spirit of the gospel, and that it is so commended by the example of the saints, that the neglect thereof is a strange inconsistency...

I agree with Matthew Henry when he says, "They that pray in the family do well; they that pray and read the Scriptures do better; but they that pray, and read, and sing do best of all." There is a completeness in that kind of family worship which is much to be desired.
