What was the fall of man?
Here's the answer:
The fall of man happened when the first people brought sin into the world.
When the Bible talks about "the fall of man," it’s saying that man fell out of Gods perfect plan for them—which was to live in peace and harmony with God, the world, and each other.
In the beginning, everything was perfect. Adam and Eve didn't have to suffer any hard times or pain because they were close friends with God and sin didn’t exist. God provided for their every need, and all they had to do was enjoy it.
However, God gave them one command: not to eat from the tree of the knowledge of good and evil (Genesis 2:16–17). The devil came along, who disguised himself as a snake, and he tricked Eve into believing that if she ate of the tree of knowledge of good and evil she would be wise just like God. So she ate the fruit, and she gave some of it to Adam to eat too (Genesis 3:2–6).
As soon as they ate that fruit, they were separated from God because God is holy (perfect) and can’t be in the presence of sin or evil. This event was called "the fall."
Adam and Eve introduced sin into the world by disobeying God, and because of that every person born afterward has a desire to be naughty and sin. But God loves us so much that He made a way for us to be forgiven of our sin. The only way to be forgiven is through God's Son, Jesus (John 14:6). Read more about that here.
"Sin entered the world because one man sinned. And death came because of sin. Everyone sinned, so death came to all people...God’s gift is different from Adam’s sin. Many people died because of the sin of that one man. But it was even more sure that God’s grace would also come through one man. That man is Jesus Christ. God’s gift of grace was more than enough for the whole world" (Romans 5:12; 15).
"God loved the world so much that he gave his one and only Son. Anyone who believes in him will not die but will have eternal life" (John 3:16).
