"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' (Phil. 4:6), is unlimited, and so is the verse, 'Cast all your anxiety on him' (1Peter 5:7).
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, 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."
