A Christian must believe that…

God is a person who created all material and spiritual substance, and that out of the created material He personally formed the worlds and each creature therein:

Genesis 1:1

In the beginning God created heavens and the earth.

Genesis 2:7

The Lord God formed the man from the dust of the ground and breathed into his nostrils the breath of life, and the man became a living being.

Genesis 2:19

Now the Lord God had formed out of the ground all the beasts of the field and all the birds of the air.

Psalm 8:1-9

O Lord, our Lord, how majestic is your name in all the earth. You have set your glory above the heavens. From the lips of children and infants you have ordained praise because of your enemies, to silence the foe and the avenger. When I consider you heavens, the work of your fingers, the moon and the stars, which you have set in place, what is man that you are mindful of him, the son of man that you care for him? You made him a little lower than the heavenly beings and crowned him with glory and honor. You made him ruler over the works of your hands; you put everything under his feet: all flocks and herds, and the beasts of the field, the birds of the air, and the fish of the sea, all that swim the paths of the seas.

Psalm 102:25

In the beginning you laid the foundations of the earth, and the heavens are the work of your hands.

John 1:3-4

Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of men.

Ephesians 3:9

And to make plain to everyone the administration of this mystery, which for ages past was kept hidden in God, who created all things.

Colossians 1:15-18

He is the image of the invisible God, the firstborn over all creation. For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by him and for him. He is before all things, and in him all things hold together. And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy.

Hebrews 1:1-3

In the past God spoke to our forefathers through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son, whom he appointed  heir of all things, and through whom he made all the universe. The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven.

Revelation 4:11

“You are worthy, our Lord and God, to receive glory and honor and power, for you created all things, and by your will they were created and have their being.”
