2 Cor. 5:17 "If any one is in Christ He is a new creation. What is old has passed away; look! What is new has come!"
Do you kids sing? Do you know that songs are the best way to easily memorize those things you really want to remember. I can recall the words to a song from a very long time ago. Bringing up those lyrics is a refreshing way to remember God's Word. Even if the child does not really understand those words now, some time in the future he or she will remember those words from a prompting by the Holy Spirit and those words will come to life.
