Defiance against God.

"But the person, native, or foreigner, who sins defiantly, deliberately blaspheming God, must be cut off from his people: He has despised God's word, he has violated God's command; that person must be kicked out of the community, ostracized, left alone in his wrongdoings." Numbers 15:30-31, The Message

Defiance of God and His Word only brings calamity on ones own-self, and on loved ones.  So, tread extremely lightly my friend if you knowingly decide to sin, because the sin you commit will, (and let me emphasize will), without fail, come back and bite you right in the fanny.

In a nutshell.

Ezekiel, Chapters 24 – 26, in a nutshell:

The evil, vengeance, pride, haughtiness, contempt, arrogance, hurt, destruction, death, resentment, un-forgiveness, rejection, darkness and desolation, that you bring onto others, will eventually be brought back onto you; less you stop immediately, seek forgiveness from God, turn from your wicked ways, and begin to do what the Word of God tells you to do.

My friend, if you knowingly continue in your current sins, and do not decide to stop and seek the forgiveness of God, then you will pay the price!  Guaranteed!
