“To inculcate” means “to teach and impress by frequent repetitions.” To do so, parents need to spend time regularly with their young ones. It could at times seem frustrating to have to repeat instructions to the children. However, parents can strive to see this as a way to help their children understand God’s Word and apply it. So be discerning. Psalm 127 compares children to arrows. (Ps. 127:4) Just as arrows can be made from different materials and can vary in size, no two children are precisely alike. So parents need to determine how to train each of their children. A couple in modern-day Israel who successfully raised two children to serve Jehovah tell what they found to be helpful, “We conducted a Bible study with each child separately.” Of course, each family head will decide whether studying in that way is necessary or possible. w19.12 26-27 ¶18-20
