Parents, let our countenances reveal constantly the peace and consolation of Christ. This is a missionary work that you are able to do at home. Missionary work begins in the home. Educate and train your children for the future immortal life. Lead them to give their hearts to God, that they with you may be numbered among His people. You can teach them to stand by you, to strengthen your hands in the missionary work; and in turn, you can strengthen them. PCP 28.3
Parents, sanctify yourselves, that your children also may be sanctified. Sanctify your talent of speech. Words are a precious gift, capable of doing much good and accomplishing a great work for the Master. Let every word be such that you can have it written in the books of heaven without being ashamed to meet your record in the judgment. PCP 28.4
