"And God said, 'Let the water teem with living creatures, and let birds fly above the earth across the expanse of the sky.' So God created the creatures of the sea and every living and moving thing with which the water teems, according to their kinds, and every winged bird according to its kind. And God saw that it was good." NIV translation
Once the earth was ready to sustain life, God created creatures to fill the water and the air. God created them for us to enjoy and saw that it was good.
"God blessed them and said, 'Be fruitful and increase in number and fill the water in the seas, and let the birds increase on the earth.' And there was evening, and there was morning - the fifth day." NIV translation
Throughout the Bible, the number five is associated with grace. This passage is a picture of the magnitude of God's grace, in that, He not only created the life in the seas and the air but caused them to multiply. Even at this early point in time, God knew that this life was going to be affected by sin and, even then, He was prepared to send His Son as payment. God continued to bring forth life even as He knew that it would require His Son to go to the cross. That, my friends, is the magnitude of His grace!
"And God said, 'Let the land produce living creatures according to their kinds: livestock, creatures that move along the ground, and wild animals, each according to its kind.' And it was so. God made the wild animals according to their kinds, the livestock according to their kinds, and all the creatures that move along the ground according to their kinds. And God saw that it was good." NIV translation
At the start of the sixth day, God created all of the animals. We see that God created all of the different kinds and said that it was good. That reminds us that God loves diversity in life and that all things have a God given purpose (even those animals that we do not like and consider to be pests). The same goes for people and we should not condemn what God has called good. All life has a God given purpose and is precious in His sight!
"Then God said, 'Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground.' So God created man in his own image, in the image of God he created him; male and female he created them." NIV translation
God created us in His image and appointed us to be the caretakers of all that He created. Out of all that was created, we are the only things that this is said about and that sets us apart. No matter what anyone else may say about you, always remember that you were created in the image of God and He does not make junk! A caretaker is someone that works for the owner to look after his stuff. We need to remember that we do not own anything that God has created; He simply allows us to take care of it for Him and to enjoy it but every caretaker answers to the owner for their work. This answering is described in Revelation chapter twenty and is commonly called the "judgment of rewards".
