This means to know God’s Word so well that it keeps you close to Him. He is alive, and wants a relationship with you. So, when you read His Word, it’s alive, and able to speak to you. It’s just like the Matthew 6:33 example. I knew it once I stopped pressing myself, because I had hidden that verse in my heart.
That verse goes on, though – we should do it so we might not sin against God. When you read the Word of God, you can do it with others. Younger children will only need short passages to discuss, but even something as simple as Ephesians 4:26 can be remembered by a young child, as a key to reconciling quickly, instead of staying mad at someone. It says, “Be ye angry, and sin not; let not the sun go down upon your wrath.”
From what we know elsewhere, we know that this verse means it’s okay to be angry if it’s righteous anger. However, we should never let that anger cause us to sin. We should also never let the sun go down before our wrath is finished. In other words, make up with someone right away, instead of letting that wrath boil overnight.
