Why are people full of fear of the world?

Because people leave God, there is no inner peace. Everything is created by God, and God lets people manage it. Since Adam and Eve didn't believe in God, sin has entered people's hearts, and people's hearts have fear.

Adam and Eve disobeyed God's command and ate the fruit of the tree of good and evil. At that time, when they heard the voice of God, they were afraid to hide. God called and said, "Adam, where are you?" Adam said he was afraid to hear the voice of God. In fact, the voice of God is kind, but people are lost.

Only by knowing the salvation of Jesus Christ can we find true peace. So there is a saying called "Christmas Eve"

Welcome Jesus and there will be real peace. Bless you.
