Read the Bible.

"Heads of families must read the Scriptures to their families and instruct their children and servants in the matters and doctrines of salvation. Therefore, they must pray for and with their families. No one who does not want to deny the Scripture can deny the unquestionable right to read the Bible in our homes, the governors of families must teach and instruct their families with the Word of God."
