Deut 6 instructs parents to teach the Word of God to their children at all times. We cannot change their hearts, that is of the Lord, but as believing parents, we are called to be obedient to His word. We (children and adults included) should hide God's word in our heart. Hebrews 4:12 says, "For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart." May the Holy Spirit use the Word implanted in all of our hearts to make us more like Christ in all ways.
