Angels cannot preach the gospel, only beings such as Paul and you and I can preach the gospel.
Oswald ChambersOur Lord never referred to unanswered prayer. He taught that prayers are always answered: โEveryone who asks receivesโ. And He implied that prayers are answered rightly because of the heavenly Father's wisdom: โYour Father knows the things you have need of before you ask Himโ.
