Andre Previn said, "If I miss a day of practice, I know it.  If I miss two days, my manager knows it.  If I miss three days, my audience, knows it."  He was talking about the piano, but the same is true about your devotional life.  When you're spending time with God on a consistent basis, it shows.  When you aren't also shows.  You'll notice it first, then those closest to you, and, pretty soon, it's obvious to everyone.

 A little girl sitting on the front steps of her home was singing the song, “Jesus Love Me, This I Know.”  A neighbor who had no time for God heard the song and it reminded him of days long gone by when he was a small boy in Sunday School.

“How do you know Jesus loves you,” he called to the child.  “Have you seen him?” 

“No, Mr. King, I haven’t seen him but I talk to him every night.”  The child went right on singing about Jesus.
