The answer
We worship One God, “For there are Three that bear record in heaven, the Father, the Word, and the Holy Spirit: and these Three are One” (1 John 5:7).
From this, we have: the Being of God (the Father), the Mind of God (the Son), and the Spirit of God (the Holy Spirit). The Three are One.
If man was created in the image of God and His likeness, then he was created according to an image: a human being, a mind, a spirit, and the three are one.
When we speak of your nature, we say that you have: a mind or a self, reasonable (rational) speech, and a spirit. Speaking of your nature does not negate at all that you are one, and not three.
