Can we call Jesus God?

The Apostle John in affirming the deity of Jesus Christ in John 1:18, “No one has ever seen God; the only God, who is at the Father’s side, he has made him known”. Thus showing oneness of essence between Father and Son. In addition, Apostle John mentions in John 10:30, “I and the Father are one.” Thereby bearing upon the essential unity. It is interesting that whether the word “one” is neuter in gender, or literally, one thing.
