How about the rest of the words?In some Christian music, a house is used to symbolize the body housing the soul.
Or it can symbolize the "mansion" of heaven.
Or it may be one of those songs that goes on to talk of dear mother praying; there are a lot like that.
Or it can be about supper, which would refer to the Lord's Supper, communion... or to the heavenly banquet, or the table spread in Psalm 23 before one's enemies...
Hafta see the rest of the words, these are just possibilities.
