"I have come that they may have life, and that they may have it more abundantly." - John 10:10 -

What it boils down to is this:

There is one God. God created all things: the heavens and the earth and all that exists in them. He is eternal one God in three persons – God the Father, God the Son, and God the Holy Spirit. These three are equal and are one God. Genesis 1:1; 2 Corinthians 13:14; Psalm 90:2; 1 Peter 1:2
