If I heard it once, I heard it a hundred times that we are all children of God. I have even heard it from behind the pulpit. Either it is a lie or Jesus lied. I am going to believe Jesus.

When Jesus was being confronted by the pharisees, (John 8:40 to 48) He said that their father was the devil and that they did the will of the devil.

While all men and women are created by God, not all men chose to be his children. Instead they chose to follow Satan. When a person chooses to not follow God, then he follows Satan and Jesus, according to this passage, says that their father is the devil.

Only when a person accepts Jesus as his savior and master does a person become the child of God. Once a person becomes a child of God, that is permanent. It is irreversible. Argue with me if you like. First read the passage. Read what Jesus has to say on the matter. Read John 3:16 and 17. (Note, if eternal life might be reversed, then it is not eternal.)
