Once upon a time many years ago.
I was teaching my two boys ages 3 and 4 years old to sing, Jesus Loves Me. The words are....

Jesus loves me! This I know,
For the Bible tells me so.
Little ones to Him belong;
They are weak, but He is strong.

Yes, Jesus loves me!
Yes, Jesus loves me!
Yes, Jesus loves me!
The Bible tells me so.

All day I was singing it and having them sing along with me. Over and over we'd sing. When Dad got home from work we sang it together for him. "Look what we learned today Dad!" Finally it was bedtime, I say to the boys, "Okay now you guys sing it for me Let's see if you really know it." In perfect unison, the sweetest singing in their little voices ...... Jesus loves Mom this I know.
