When and how did God create the universe? The Bible tells us that he created the heavens and the earth “in the beginning.” We discussed that truth last time. But how did he create? Remember there was nothing to create with. There was no material in existence to make something out of. And “God said, ‘Let there be light'” (Genesis 1:3). “Then God said, ‘Let there be a firmament'” (Genesis 1:6). God’s method of creation was to speak. Psalm 33:6 “By the word of the Lord the heavens were made, And all the host of them by the breath of His mouth.”
God spoke and the universe and all it contained came into existence. He continued to speak and various parts were separated from other parts. For example water on the earth was separated from water above the earth and an expanse was created between them. Light and darkness were separated from one another. Water was gathered together into one place to allow the dry land to appear. All of these things occurred because God spoke. God created through the spoken word.
When we look at John 1, we find that the Word was in the beginning with God and the Word was God. But the Word became flesh and lived among us. This Word is the second person of the trinity. He is the Word of God and he is God. And that Word took on a human body and his name is Jesus of Nazareth, the Son of God, the Messiah. All through the description of Jesus’ ministry here on earth he says things like, “I do nothing of Myself; but as My Father taught Me, I speak these things” (John 8:28). And, “For I have not spoken on My own authority; but the Father who sent Me gave Me a command, what I should say and what I should speak” (John 12:49).
Jesus is God’s Word to man and it is through him that all things were created.
Hebrews 1:1,2 God, who at various times and in various ways spoke in time past to the fathers by the prophets, has in these last days spoken to us by His Son, whom He has appointed heir of all things, through whom also He made the worlds;
Colossians 1:16 For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him.
The answer then to how God created the universe is that God spoke the word and everything came into existence and that Word ultimately took on bodily form and came here to dwell with us – Jesus Christ.
