Yes. Scripture often speaks of the angels. Christ Himself taught their existence. Human experience of their influence leaves no doubt on the subject. And it is reasonable that God should have completed the hierarchy of created beings by producing purely spiritual creatures in addition to merely material and semi-material beings. Not all evidence depends upon sense-experience. I have never seen an angel. I am not now in a normal condition to see one, and do not expect to do so until I reach heaven. I still belong to the material world. But I believe the word of God, who should know whether or not angels exist.
