Under Gods command

Deuteronomy 4:23-24 Be careful not to forget the covenant of the Lord your God that he made with you; do not make for yourselves an idol in the form of anything the LORD your God has forbidden.  For the LORD your God is a consuming fire, a jealous GOD ( God is a consuming fire.  Because he is morally perfect, he hates sin and cannot accept those who practice it.  Moses’ sin kept him from entering the promised land, and no sacrifice could remove that judgment.  Sin kept us from entering God’s presence, but Jesus Christ paid the penalty for our sin and removed God’s judgment forever by his death.  Trusting in Jesus Christ will save you from God’s anger and will allow you to begin a personal relationship with him.  Jealousy is  a demand  for someone else’s exclusive affection or loyalty.  Some jealousy is bad.  It is destructive for a person to get upset when his or her spouse talks to someone of the opposite sex.  But other jealousy is good.  It is right for a man to demand that his wife treat him, and only him, as her husband.  Usually we use the word jealousy only for the bad reaction.  But God’s kind of jealousy is appropriate and good.  He is defending his word and guarding his high honor.  He makes a strong, exclusive demand on us: We must treat only the Lord, and no one else in all the universe as God.)
