To make such a service what it should be, thought should be given to preparation. And parents should take time daily for Bible study with their children. No doubt it will require effort and planning and some sacrifice to accomplish this; but the effort will be richly repaid. [Sidenote: _Personal Influence and Example_] As a preparation for teaching His precepts, God commands that they be hidden in the hearts of the parents. “These words, which I command thee this day, shall be in thine heart,” He says; “and thou shalt teach them diligently.”[312] In order to interest our children in the Bible, we ourselves must be interested in it. To awaken in them a love for its study, we must love it. Our instruction to them will have only the weight of influence given it by our own example and spirit. [Sidenote: _Abraham an Illustration_] God called Abraham to be a teacher of His word, He chose him to be the father of a great nation, because He saw that Abraham would instruct his children and his household in the principles of God’s law. And that which gave power to Abraham’s teaching was the influence of his own life. His great household consisted of more than a thousand souls, many of them heads of families, and not a few but newly converted from heathenism. Such a household required a firm hand at the helm. No weak, vacillating methods would suffice. Of Abraham God said, “I know him, that he will command his children and his household after him.”[313] Yet his authority was exercised with such wisdom and tenderness that hearts were won. The testimony of the divine Watcher is, “They shall keep the way of the Lord, to do justice and judgment.”[313] And Abraham’s influence extended beyond his own household. Wherever he pitched his tent, he set up beside it the altar for sacrifice and worship. When the tent was removed, the altar remained; and many a roving Canaanite, whose knowledge of God had been gained from the life of Abraham His servant, tarried at that altar to offer sacrifice to Jehovah. No less effective to-day will be the teaching of God’s word when it finds as faithful a reflection in the teacher’s life. [Sidenote: _Original Study_]
