This verse has had me thinking about little children...
How they depend on their parents for everything. And they simply trust that what ever they need - clothing, food, comfort, etc - will be given to them by the adults they trust.
They look up to us for guidance and knowledge. To be examples to them of what to do and how to act.
When they are happy they come to share their joy with us. And when they are sad or hurt they turn to us for comfort and expect we will hold them and make it all better.
That is how we need to be with God, isn't it? Depending on Him, and having full faith in Him. Looking to Him for guidance and wisdom. Leaning on Him in times of trouble or sadness.
Seems so simple, doesn't it?
