Because He can not lie, Lucifer is all lies, God is all truth.

2 I will give worship before your holy Temple, praising your name for your mercy and for your unchanging faith: for you have made your word greater than all your name.

Psalms 138:2.

When the fall came, God said to Adam: do not eat the fruit, or you will die. And He did not lied, Adam was immortal, and we are no longer immortal. He always keeps His promisses, that is why Lucifer wants to prove him a liar, at least once, because God made His word greater than his own name: there is no lie in Him.

The fall is when Lucifer was cast out of heaven:

14 And the Lord God said to the snake, Because you have done this you are cursed more than all cattle and every beast of the field; you will go flat on the earth, and dust will be your food all the days of your life:

15 And there will be war between you and the woman and between your seed and her seed: by him will your head be crushed and by you his foot will be wounded.

Genesis 2.

The seed of the woman (Jesus) was hurt by Satan, the crucificion, but He (Jesus) will destroy Satan in the end (hurt his head). God predicted everything in that very day and He never lies, that is why He did not destroyed Satan there, he was a god, a son of God, he was loved by god:

You were the anointed cherub who covers, And I placed you there. You were on the holy mountain of God; You walked in the midst of the stones of fire. 15"You were blameless in your ways From the day you were created Until unrighteousness was found in you. 16"By the abundance of your trade You were internally filled with violence, And you sinned; Therefore I have cast you as profane From the mountain of God. And I have destroyed you, O covering cherub, Ezekiel 28:15.

Because it would not mean anything to God, since mount Zyon (in Israel) is God´s favorite place on Earth and the jews are the people He have chosen. That is whhy it hurts so much to God see this happening.

I will Open My Mouth in Parables
…67He also rejected the tent of Joseph, And did not choose the tribe of Ephraim, 68But chose the tribe of Judah, Mount Zion which He loved.69And He built His sanctuary like the heights,  Psams 78:68.

First of all, if you actually read my post, I said superscede the part you quoted. The entire point of Christinaity, is that the arrival of the Messaih/Christ changed everything, thus the New Testament overwrites the old.

Second of all, The Bible is book of an interpretation. Just like you read the Bible as homophopic, others can take away different things, anyone can form an opinion. 

You claim your a decent human being, yet you are being intolerant because of your ignorance and your willingness to believe religion is some how evil, just like the extremist you claim to hate, and those who continue to beleive that the earth is flat.

You are exactly the kind of person that you are condeming, being willingly ignorant is the same reason why people believe religion somehow prevents Science. Being willingly ignorant is basically responsible for the greatest evils in this world.

Nazi's got in power in germany, because people were willingly ignorant and let it happen.

Same thing with Jim Crow in Americans.

Pathetic.

Seems like you are the one brainwashed, can't even be open to any and all ideas because you are afraid that your beliefs might be compromised, thats the same kind of mentality that makes people kill in the name of Religion.

I agree, I think that any kind of ideology should never become illegal, however certain acts related to ideologies and religion should keep being regulated or banned altogether (such as buriyng your wife alive for cheating or other less dramatic stuff).

God has a... penis? that would make Him capable of sexual reproduction with a Goddess being, who could then give birth to a more adapted being than themselves, If God has a gender that would mean he's an imperfect being.

Old testament is Judaism, New Testament is Christianity.

Nonetheless, Bible is a book of interpretation, Christianity (and pretty much all Religions) are belief systems based on faith. Applying Rationality to its pointless.

Understand, Religion is simply a construct of humans to explain things that they don't understand. The expanse of science eliminates the need for Religion which is an inevitable process. Religion does not conflict with Science, people afraid of losing power does. Since Science depends on observation by definition, it is limited by our perception. Thus their will always be a reason for Religion.

As for the the tenets of different religion, freedom of belief.

People do not have freedom to do whatever they want, namely break the law regardless of whether or not they claim its in the name of Religion.

Could you imagine these people's reactions if a new Son of God arrived and just said "you know what, f* the New Testament, here's a revised Newer Testament, bye".

For Instance, if you want to see where God is, he's some where in the statically bits if you move the slider all the way to the right. There are also dragons, unicorns, Fem-God, the winning lotto ticket, your dreams, and the Last Guardian there.

Most Certainly.

That probably won't happen. Even if it did, Religion will never die out.
