"Thou shalt teach them diligently
unto thy children.”
Deuteronomy 6:7
What should you teach them?
To love the Lord God with all their heart (Deut. 6:5).
Who should be taught?
Your children (v. 7), and the responsibility doesn't stop there. We are to teach our grandchildren also (Deut. 4:9). Timothy knew the blessing of learning of "the unfeigned faith" from both his mother and grandmother (2 Tim. 1:5).
When should it be taught?
When sitting at home, when walking by the way, when lying down and rising up—continually (Deut. 6:7).
