Friend, you do not know any more than they did what you are doing in your rebellion against the idea of yielding to God. Little did those people know or realize to what depth sin had taken them. Many, because they still go to church, fail to realize what is happening to them. Oh, you like to think that you are much better off than what you really are, but whenever God speaks, it is symbolic of the shape and the condition in which He sees you. Many people in our world start in the sin career without thinking about what they are dealing with.
Sin is no plaything, because sin is no one's friend.
The Bible shows sin to be very deceptive. He was talking to brethren. He does not even enter this picture now. In other words, Paul said to watch yourself, lest there be in you an evil heart. An evil heart of unbelief causes people to go away from Christ instead of coming to Him.
