None of condemned thing shall be found in your hands

Deuteronomy 13:1-18
The Lord your God, who redeemed you out of Egypt and redeemed you from the land of slavery.
You must purge the evil from among you.
If someone among you says the sign or  wonder of which he has spoken takes place, and says Let us follow other gods". The Lord is testing you to find out whether you love him with all your heart and with a your soul.
If your very own brother, son or daughter, or wife or closest friend secretly entices you go and worship other gods, do not yield to him or listen to him. Show him no pity.
None of those condemned thing shall be found in you hands, so that the Lord will turn from his fierce anger, he will show you mercy, have compassion on you.
Why?
The dreams are random event in our mind, if there is an evil mind is the Lord test us whether us our faith to Him. Don't think about the Lord will ask us to do the evil thing.
So severely treat our loves people is remind us to follow the commands of the Lord is more important than love our relatives or friends. Because it will cause us go well or bad.
The danger of being enticed away to false religions was very real. Anyone found on investigation to have encouraged this must be made an example of and destroyed.
How?
Love the Lord with all my mind, all my soul and all my strength. For He is the only on God, have mercy and mighty hands, He redeemed me from the slavery of dead.
