God sent you a letter, it has no return address. It simply has your name on it. He wants you to know that he is listening. He wants you to know that he is waiting. You don't need a stamp to respond, you need only call on his name. He waits patiently for his children to call back, but many never do. So if you missed his letter, there is still time. The invitation to talk to him is still open. Just find a quiet place and invite him to stop by. He will be glad to hear you call.
