Hebrews 11:1

Genuine faith puts its letter in the mailbox and lets go. Distrust, however, holds on to a corner of the envelope and then wonders why the answers never arrives. There are some letters on my desk that I wrote weeks ago, but I have yet to mail them because of my uncertainty over the address or the contents. Those letters have not done any good for me or anyone else at this point. And they never will accomplish anything until I let go of them, trusting them to the postal service.

Dr. Payson, while still a young man, once wrote to an elderly mother who was extremely worried and burdened over the condition of her son. He wrote,
You are worrying too much about him. Once you have prayed for him, as you have done, and committed him to God, you should not continue to be anxious. God's command, "Do not be anxious about anything" is unlimited, and so is the verse, "Cast all your anxiety on him". If we truly have cast our burdens upon another, can they continue to pressure us? If we carry them with us from the throne of grace, it is obvious we have not left them there. In my own life I test my prayers in this way:after committing something to God, if I can come away, like Hannah did, with no more sadness, pain, or anxiety in my heart, I see it as proof that I have prayed the prayer of faith. But if I pray and then still carry my burden, I conclude my faith was not exercised.

When we nailed our concerns, anxieties and worries upon the old rugged Cross, have we left them there or still carry them with us? Extracted from Streams of the Desert
