We must go to the New Testament to find how God wants us to worship Him today. Literal language is the type which is found in the historical books of the Bible such as Genesis and Exodus, the book of Acts, etc. It is fact. Literal words must be understood to have their actual meaning. In literal language, if a sheep is mentioned, it means a four legged animal which has wool on its back.
Figurative language is different.
Words are used to represent ideas or thoughts which are different from the actual meaning of the word. It is being used to represent something else which has some of the qualities of a sheep or lamb. Jesus was a man. He is the Son of God. But in figurative language in the Bible, He is sometimes spoken of as a lamb.
