The book of Genesis is the book of beginnings and there are many beginnings in the book. It is worth mentioning it is the first book in the bible. Genesis means the formation of something and in Genesis 1 God formed the creation, universe and man.
He formed man by His own creative hands and he created the heavens, the earth, and the universe by the word of His mouth. We read in Genesis 1:26-30 “Then God said, “Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals,[ and over all the creatures that move along the ground.”So God created mankind in his own image, in the image of God he created them; male and female he created them. God blessed them and said to them, “Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish in the sea and the birds in the sky and over every living creature that moves on the ground.” Then God said, “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food. And to all the beasts of the earth and all the birds in the sky and all the creatures that move along the ground—everything that has the breath of life in it—I give every green plant for food.” And it was so.

Man was God’s crowning creation in Genesis and He gave man and only man the dominion to rule the earth. He told man to multiply and fill the earth. He gave man the trees to eat from and animals to eat.
God crowned man with His glory for you see Adam and Eve were naked but the glory of God covered them. Literally, the light of God surrounded them. We were the only creation that God made in His image. What an honor that man was created in the image of God.
God walked only with Adam and Eve in the garden and talked with them. He fellowshipped with man not the animals, stars, or the plants. Man was the only creature that had intimate contact with God. God desired a family when He created man in the beginning of time.
In the book of Genesis, we know that Abraham gave Melchizedek the first tithe recorded in the family. This same Abraham was the first man to receive the promise of God who promised Him that all families on the earth would be blessed through Abraham.
God promised Abraham and Sarah they would have a child of promise well into their old age. This was the first promise God made to an elderly couple in the bible. Abraham was about 100 years old and Sarah was 90 years old when Isaac was born. Isaac was the sign that Abraham would be a blessing to all the families on the earth. Genesis is the book of beginnings.
