It's nice to be as innocent as a child and as an adult I can really learn from them a lot of the time.
We do teach our kids about right and wrong and when I know that my daughter is lying I remind her that God knows if she is lying or not.
The one evening after I read her a book and prayed with her; she asked me if she could pray. I said of course she can. She then told me that I must not listen and I said okay I won't. Naughty me - I listened. She had told God that she was sorry for lying.
After she had said "amen" she asked me if I listened...
My answer was "no".
I had to do lots of repenting for lying after that. But I knew from previous experience that she can really get upset if things are not done correctly.
One day when she's older I'll share this story with her and she can laugh at me.
Matthew 19:14 Good News Translation (GNT)
