So what we have so far is the Father, the Son and the Holy Spirit are 3 separate persons. All 3 persons are called God and there is only one God. We find this in creation also. All 3 are called the creator and there is only one creator.

THE FATHER IS CREATOR
Isa 45:18 For thus says the LORD, who created the heavens (He is the God who formed the earth and made it, He established it and did not create it a waste place, But formed it to be inhabited), "I am the LORD, and there is none else. ( see also Isa 42:5 & 1 Cor.8:6)

JESUS IS CREATOR
Col 1:13-16 For He delivered us from the domain of darkness, and transferred us to the kingdom of His beloved Son, in whom we have redemption, the forgiveness of sins. And He is the image of the invisible God, the first-born of all creation. For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities-- all things have been created by Him and for Him.
(See also John 1:3, Hebrews 1:2, 1 Corinthians 8:6)

THE SPIRIT IS CREATOR
Job 26:13 By his spirit he hath garnished the heavens; his hand hath formed the crooked serpent.           

Gen 1:2 And the earth was formless and void, and darkness was over the surface of the deep; and the Spirit of God was moving over the surface of the waters.
          (see also Ps.104:30)

GOD CREATED BY HIMSELF
Isa 44:24 Thus says the LORD, your Redeemer, and the one who formed you from the womb, "I, the LORD, am the maker of all things, stretching out the heavens by myself, and spreading out the earth all alone,
           
          He could not say he created "by myself" and "all alone" if the Father, Son & Holy Spirit were 3 separate Gods. To some people these verses would seem to be in conflict with each other. They are not however in conflict at all. The answer is these 3 persons constitute only one God.

Deut 6:4 "Hear, O Israel! The LORD is our God, the LORD is one!

           We find further plurality in the one God in the Old Testament. For example:
Gen 1:26-27 Then God said, "Let Us make man in Our image, according to Our likeness; and let them rule over the fish of the sea and over the birds of the sky and over the cattle and over all the earth, and over every creeping thing that creeps on the earth." And God created man in His own image, in the image of God He created him; male and female He created them.

          Notice "Us" & "Our" are plural. Notice also that "His" & "He" are singular. My point again is there is plurality in the one God. There is not 3 Gods, but rather 3 persons in the 1 God.
