Prayers prayed in the Spirit never die until they accomplish God's intended purpose. His answer may not be what we expected, or when we expected it, but God often provides much more abundantly than we could think or ask. He interprets our intent and either answers or stores up our prayers. Sincere prayers are never lost. Energy, time, love, and longing can be endowments that will never be wasted or go unrewarded.
