I know that we can all grow weary in the constant sharing and teaching about our Lord and His Word and wonder if our children will ever "catch on", so I thought that I would share a few wise words as an inspiring reminder to be faithful in training from a 17th century preacher on training our children to know the Bible:
"Train your child to a knowledge of the Bible. You cannot make your children love the Bible, I allow. None but the Holy Spirit can give us a heart to delight in the Word. But you can make your children acquainted with the Bible; and be sure they cannot be acquainted with that blessed book too soon, or too well.
A thorough knowledge of the Bible is the foundation of all clear views of religion. He that is well-grounded in it will not generally be found a waverer, and carried about by every wind of new doctrine. Any system of training which does not make a knowledge of Scripture the first thing is unsafe and unsound.
See that your children read the Bible reverently. Train them to look on it, not as the word of men, but as it is in truth, the Word of God, written by the Holy Ghost Himself- all true, all profitable, and able to make us wise unto salvation, through faith which is in Christ Jesus.
See that they read it all. You need not shrink from bringing any doctrine before them. You need not fancy that the leading doctrines of Christianity are things which children cannot understand. Children understand far more of the Bible than we are apt to suppose.
Tell them of sin, its guilt, its consequences, its power, its vileness: you will find they can comprehend something of this. Tell them of the Lord Jesus Christ, and His work for our salvation- the Atonement, the cross, the Blood, the sacrifice, the intercession: you will discover there is something not beyond them in all this.
Tell them of the work of the Holy Spirit in man’s heart, how He changes, and renews, and sanctifies, and purifies: you will soon see they can go along with you in some measure in this. In short, I suspect we have no idea how much a little child can take in of the length and breadth of the glorious Gospel. They see far more of these things than we suppose. Fill their minds with Scripture. Let the Word dwell in them richly. Give them the Bible, the whole Bible, even while they are young."
