Your children have souls, and they must be born again by God, or they will perish. And also understand, that unless you are very prudent in your behavior to and before them, they may perish because of you: the thoughts of which should provoke you, both to instruct, and also to correct them.
First, to instruct them as the Scripture says, “bringing them up in the training and instruction of the Lord;” “Impress [the truths of the Word of God] on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up.” [Ephesians 6:4; Deuteronomy 6:7]
