World renowned evangelist Billy Graham revealed what he thinks is the greatest spiritual mistake people often make. Graham wrote in a May 2 post for his Billy Graham Evangelistic Association’s website that when it comes to spending your life in eternity, your good acts are not enough to God.

This is because according to the Bible, the only way we could reach God’s standard of goodness is by being completely perfect. Graham cites Habakkuk 1:13, which reads: “Your eyes are too pure to look on evil; you cannot tolerate wrongdoing.”
