I finally understand the meaning of knowing something by heart. It means that this something is an integral part of you — it is dear to you. Seeing my 3-year old daughter sitting on our worn loveseat in her Sunday dress singing Psalm 4b by heart touched me in a way that few things can. Jesus loves her — and this she knows because the bible tells her so. It is as simple as that. And because of this knowledge, she loves to sing God’s praises. I even hear her singing Holy, Holy, Holy by heart to her little family as she puts Baby to bed. This truly is amazing grace.
