Genesis 1:3 - 5

"And God said, 'Let there be light,' and there was light. God saw that the light was good, and he separated the light from the darkness. God called the light 'Day,' and the darkness he called 'night.' And there was evening, and there was morning - the first day." NIV translation

God begins the renovation with the re-introduction of light and the separation from darkness to create day and night. We see that this renovation process is simple in that, God says it and it happens. Light is essential for the life that will follow because, without light, plants will not grow and without plants no other form of life could live. The last part of the passage places evening before morning and that is why the Jewish day begins at sunset.

Genesis 1:6 - 8

"And God said, 'Let there be an expanse between the waters to separate water from water.' So God made the expanse and separated the water under the expanse from the water above it. And it was so. God called the expanse 'sky.' And there was evening, and there was morning - the second day." NIV translation

On the second day, God created the sky and once again it was created out of nothing simply by God speaking it into existence.

Have you ever asked yourself why God did not just create everything on the first day and call it good? The simple fact is that He could have but chose not to in order to teach us how to live. 

There is a time for everything and many times we have to wait for God's timing as it is different than ours.

Genesis 1:9 & 10

"And God said, 'Let the water under the sky be gathered to one place, and let dry ground appear.' And it was so. God called the dry ground "land", and the gathered waters he called 'seas'. And God saw that it was good." NIV translation

Not only did God create the waters but, as we see here, He controls them. At His word, the waters moved to expose land. The waters also obeyed when He told them to part and allowed His people to escape from Egypt. They also obeyed when God sent them in judgment of the inhabitants of Noah's day. Today, it seems that many people elevate nature and its forces above God but, as we see here, God has always retained control over everything that he created. The forces of nature obey the words of God and we would do well if we did the same.
