We begin this week with the fifth day of creation. The day God formed both the birds and the seas. He formed all the diverse types of birds and sea animals at the same time. They did not evolve over millions of years and they did not develop from the plant life that was already created. Once this day was coming to an end God blessed them. He blessed them telling them to "be fruitful and multiply." They had a job to do. He had given them a purpose that only they could fulfill.
On the sixth day God moved on to the next step in His plan when He created the land animals. Notice in verse 24 just like back in verse 20 and again in other verses to follow, we are told that that each was to produce "according to its kind". God deliberately structured plenty of variation within a kind, but one kind does not become another kind. For example, structure among dogs is diverse. The teacup poodle is very different from the Great Dane, but they are both dogs. However, they won't ever become mice, no matter how much breeding is done.
He then continues His work for that sixth by creating humans in his own image. Again He blessed them and gave instructs to "be fruitful and multiply". But with the man He gave more instructions and with that more authority. He said, " Fill the whole earth and govern it. Reign over the fish of the sea, the birds in the sky, and all the animals that scurry the earth."
I love the fact that God blessed them before He gave them their directive. To me that shows that He gave them all the wisdom and ability that they would need to fulfill the duty He has sat before them. That give me hope and encouragement that He will do the same for me. God had pronounced the creation good, He really meant it. At the time it was entirely good: there was no decay on earth, yet. But once He sees the man He has created His analysis of His work He declares it to be 'very good'.
God has created us all for a purpose, given us authority, and blessed us to fulfill that purpose. Are we doing all that we were created to do ? Will He declare us to be very good ?
