The Lord your God is a consuming fire, a jealous God

Deuteronomy 4:15-31

You saw no form of any kind the day the Lord spoke to you at Horeb out of the fire. Therefore watch yourselves very carefully, so that you do not become corrupt and make for yourselves an idol, an image of any shape.

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.

If you then become corrupt and make any kind of idol, doing evil in the eyes of the Lord your God and arousing his anger, I call the heavens and the earth as witnesses against you this day that you will quickly perish from the land that you are crossing the Jordan to possess. You will not live there long but will certainly be destroyed. The Lord will scatter you among the peoples, and only a few of you will survive among the nations to which the Lord will drive you. 

For the Lord your God is a merciful God; he will not abandon or destroy you or forget the covenant with your ancestors, which he confirmed to them by oath.

The Lord is God in heaven above and on the earth below. There is no other... Keep his decrees and commands ... so that it may go well with you.

Why?

The Lord is a consuming fire, a jealous God when his people turn away and worship any idols that will have perished. It likes a woman married but betrayed his husband, his husband will abandon her.

Moses had warned Israelites before they entered the promised land. It is sad what Moses said come true and they were scattered to many countries. 

For the Lord is a merciful God, God would not abandon his covenant with his people. Always is us make the Lord sad for we are fall in the sins.

How?

Be a servant of the Lord, give up myself, and obey God's word. For God is good.
