Certain times in my life I have experienced a feeling of helping angels.
Recently I pray with groups at certain times for the salvation of the nation. Some too early so I have asked the Lord to wake me up if it is that important. Well, twice I have had a knock on the bedroom wall when nobody else in house.Once in the fall and other in the winter. I heard like a human knock.
Praise Jesus!
Hebrews 13:2 (New International Version)
2Do not forget to entertain strangers, for by so doing some people have entertained angels without knowing it.
