“Thou shalt teach them diligently unto thy children." Deut. 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 (Deut. 6:7), 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? Why, when sitting at home, when walking by the way, when lying down and rising up-continually. (Deut. 6:7).
