No, that is not what I believe. I believe that God reveals what humans need in every age. The spiritual teachings are essentially the same in every religion, but the social teachings and laws and the message differ according to the needs of the times.
What causes the drama and religious wars are religious people who cling to their different religions and believe that only their religion is true, that it is the best and last religion God will ever reveal.
So it is humans who cause all the problems, not God.
What would be rational would be to realize that all the religions are from the same God and each religion was the truth from God suited to the times in which it was revealed. It would be best if all religions united under one banner, but in lieu of that if they understood what I just said and accepted each other's religions they could learn to live together in harmony and unity.
You keep claiming all these "spiritual teachings", but you have never presented any no matter how many times I've asked for them. Mostly going into all kinds of avoidance tactics, even making personal attacks to AVOID presenting any.
And if you knew anything about even some of the religions, you would know that there is no way that ALL the religions would "live together in harmony and unity".
Why the Christian "god" even tells his followers this:
Exodus 22:20
"Whoever sacrifices to any god other than the LORD must be destroyed.
Deuteronomy 13:6-10
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. Your hand must be the first in putting them to death, and then the hands of all the people.
10 Stone them to death, because they tried to turn you away from the LORD your God, who brought you out of Egypt, out of the land of slavery.
Deuteronomy 13:12-16
12If thou shalt hear say in one of thy cities, which the LORD thy God hath given thee to dwell there, saying,
13Certain men, the children of Belial, are gone out from among you, and have withdrawn the inhabitants of their city, saying, Let us go and serve other gods, which ye have not known;
14Then shalt thou enquire, and make search, and ask diligently; and, behold, if it be truth, and the thing certain, that such abomination is wrought among you;
15Thou shalt surely smite the inhabitants of that city with the edge of the sword, destroying it utterly, and all that is therein, and the cattle thereof, with the edge of the sword.
16And thou shalt gather all the spoil of it into the midst of the street thereof, and shalt burn with fire the city, and all the spoil thereof every whit, for the LORD thy God: and it shall be an heap for ever; it shall not be built again.
Deuteronomy 17:2-5
2"(A)If there is found in your midst, in any of your towns, which the LORD your God is giving you, a man or a woman who does what is evil in the sight of the LORD your God, by transgressing His covenant,
3and has gone and (B)served other gods and worshiped them, (C)or the sun or the moon or any of the heavenly host, (D)which I have not commanded,
4and if it is told you and you have heard of it, then you shall inquire thoroughly. Behold, if it is true and the thing certain that this detestable thing has been done in Israel,
5then you shall bring out that man or that woman who has done this evil deed to your gates, that is, the man or the woman, and (E)you shall stone them to death.
Deuteronomy 17:12-13
12 The person who acts arrogantly, refusing to listen either to the priest who stands there serving the LORD your God or to the judge, must die. You must purge the evil from Israel. 13 Then all the people will hear [about it], be afraid, and no longer behave arrogantly.
Deuteronomy 18:20-22
20 But a prophet who presumes to speak in my name anything I have not commanded, or a prophet who speaks in the name of other gods, is to be put to death.”
