The penalty for idolatry (Deuteronomy 13: 1-2, 4, 6-8, 13-15)

Someday a prophet may come along who is able to perform miracles or tell what will happen in the future. If he says, "Let's start worshiping some new gods - some gods we know nothing about." If the prophet tells you to disobey the LORD your God and stop worshiping him, then that prophet is evil and must be put to death. Someone may say to you, "Let's worship other gods." That person may abe your best friend, your brother or sister, your son or daughter, or your own dear wife or husband. But you must not listen to people who say such things. Instead, you must stone them to death. You may hear that some worthless people have talked everyone there into worshiping other gods, even though these gods had never done anything for them. You must carefully find out if the rumor is true. Then if the people of that town have actually done such a disgusting thing in your own country, you must take your swords and kill every one of them, and their livestock too.
The grounds for idolatry are the grounds for the law as a whole. God will not share his glory with anyone or anything. God created humans to glorify himself and he created Israel as a nation to be a nation of priests to him. God does not say to reprove the offender. He says to destroy them! We will see that when Israel enters the land which is occupied by the nations, they are commanded to destroy the occupants entirely so that no sign of competing gods remains.
Daily Prayer: Father, it is no wonder that Jesus had to suffer death on the cross, because he was my sin bearer. The death penalty has been paid and we remain your people. Let me do all that is within my power to be an example of Your Kingdom to all who witness my life and to be a promoter of You and Your Son in all I say and do. In your name I pray Amen.
