Deuteronomy 13:
6 If your very own brother, or your son or daughter, or the wife you love, or your closest friend secretly entices you, saying, “Let us go and worship other gods” (gods that neither you nor your ancestors have known, 7 gods of the peoples around you, whether near or far, from one end of the land to the other), 8 do not yield to them or listen to them. Show them no pity. Do not spare them or shield them. 9 You must certainly put them to death.
This is what the Father, Son and Holy Ghost, which you believe in, ordered men to do. Kill anyone who preaches a different religion. Reading farther it only gets worse:
"12 If you hear it said about one of the towns the Lord your God is giving you to live in 13 that troublemakers have arisen among you and have led the people of their town astray, saying, “Let us go and worship other gods” (gods you have not known), 14 then you must inquire, probe and investigate it thoroughly. And if it is true and it has been proved that this detestable thing has been done among you, 15 you must certainly put to the sword all who live in that town. You must destroy it completely, both its people and its livestock. 16 You are to gather all the plunder of the town into the middle of the public square and completely burn the town and all its plunder as a whole burnt offering to the Lord your God. That town is to remain a ruin forever, never to be rebuilt."
"It is the truth from your Lord; therefore let him who will believe and let
him who will disbelieve." [Quran 18:29]
"Surely We have revealed to you the Book with the truth for all mankind; so
whoever follows the right way, it is for his own soul and whoever errs, he
errs only to its detriment; and you are not a custodian over them." [Quran
39:41]
"And if your Lord had enforced His Will, surely, all who are in the earth
would have believed together. Will you then force men to become believers?"
[Quran 10:99]
"And if God had enforced HIS will, they would not have set up gods with HIM.
And WE have not made you a keeper over them, nor are you over them a
guardian." [Quran 6:107]
