God made Adam from dust and placed him in the garden of Eden to care for it. There were two trees in the middle of the garden: The tree of life and the tree of the knowledge of good and evil. God commanded Adam not to eat the fruit of the tree of the knowledge of good and evil. The punishment for eating the fruit of this tree was death, both physical and spiritual. God put Adam over the earth and the animals, and gave him a task: To name the animals. Adam fulfilled his task by naming the animals, but he did not find a helper for him. God then made Eve from Adam’s rib to be a helper and a companion for Adam. God was over Adam and Eve because he made them, but he put Adam and Eve as agents of dominion for God in the world. Because God made them, they were supposed to obey his rules.
Eventually, a serpent talked to Eve, first bringing doubt about what God said, then tempting her to eat of the tree, saying that it would make her just like God. Eve rebelled against God and ate the fruit, disobeying his law. She also gave some to Adam, and he ate it as well. Adam and Eve became afraid of God and realized that they were naked. They covered themselves with fig leaves and hid.
The serpent was really satan in the body of a snake, who was previously an angel or heavenly being that God created. He fell because he grew prideful and wanted to be like God, and he with several angels rebelled against God. They lost, and satan and the other fallen angels (demons) were no longer in the service of God in heaven.
God punished Adam, Eve, and the snake for their sins, and promised a Savior who would crush the head of the snake (satan). God also cursed the ground, and now men had to work to get their food and deal with thorns and thistles, women would have pain in childbirth and be in submission to their husbands, and the snake would crawl on his belly. God was still merciful in all this, and did not kill them immediately, but let them live for some time. He also gave them skins to wear to cover their nakedness instead of the insufficient fig leaves. God sent them out from the garden of Eden so that they wouldn’t eat of the tree of life and live forever in their sinful condition. He also placed cherubim and a flaming sword to guard it. Adam and Eve lived outside the garden and had to deal with the effects of the curse. Eventually, they died, as would their descendants. But, many years later, God sent a Savior to save the world from their sins so that they could live with him forever, just as he promised to Adam and Eve. The Savior is God’s son Jesus, who died on the cross for the sins of the world, that whoever believes in Him would have eternal life with God in heaven instead of spiritual death; separated from Him forever.
