In summary of what i learnt: Genesis 1:2 -3
KJV:And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. And God said, “Let there be light,” and there was light.
God created two great light.
1. The first light he created was to rule the day which is the sun, known as satellite  of the earth. 
It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
2. Moon: The brightest and largest object in our night sky, the Moon makes Earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years.
Bro Eli answered a question on baptism.  
He said baptism is done in the true house of God. He also said that the true house of God is where the laws and doctrine of God is kept and observed. In keeping this laws and doctrine we will walk in holiness and become a faithful servant which will please God.
