A Sunday School teacher decided to have her young class memorize Psalm 23. She gave the kids a month to learn the chapter.
Little Billy was excited about the task, but he just couldn't remember the Psalm. After much practice, he could barely get past the first line.
On the day that the kids were scheduled to recite Psalm 23 in front of the congregation, Billy was nervous. When it was his turn, he stepped up to the microphone and said proudly, "The Lord is my shepherd, and that's all I need to know."
He was right. When it comes down to it, knowing Christ is the most important thing we can do.
