YES.  The Bible teaches there is only one God, but He exists in three persons: Father, Son and Holy Spirit (Trinity).  This is a concept that is difficult for us to understand. We accept it because the Bible tells us so.

• But unto the Son he saith, Thy throne, O God, is forever and ever: a scepter of righteousness is the scepter of thy kingdom. Hebrews 1:8
• For by him (Jesus) were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:  Colossians 1:16
  
• In the beginning was the Word, and the Word was with God, and the Word was God.... (John 1:1) And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.  John 1:14
