God has given you everything you will ever need to live your life here on earth and forever with Him in Heaven.  However, like any child there are going to be times when you're going to have a want.  Don't be afraid to tell God your wants and if they are according to His Will you can expect the provision when He knows you're ready for it.  For example, our granddaughter Gabriella a few months ago was still on baby food.  Often she would try and reach from her high-chair across the table for "grown-up" food, but we knew she just wasn't ready for it and for her own safety, knowing she just wasn't ready yet , we would withhold it from her.  Oh, believe me there were times that she would put up a fuss demanding her way, but knowing the outcome wouldn't be good we made sure she got just what she needed to grow until the time was just right for her to receive what she was reaching for.  So it is with us.  God knows exactly what and when to give us what we're reaching for.  One thing you can expect.  When you're ready, God will provide it exactly what He knows you can handle.
