What you overlook is that God updates His teachings to us periodically, and His newest teachings make quite explicit what I said above! Further, I will add this:
That's not biblical.
"Heaven and hell are conditions within our own beings."
--(From a letter written on behalf of the head of the Baha'i Faith to an individual believer, November 14, 1947.)
Well not sure if it's biblical.
These doctrines do indeed exist, but what they in fact SAY is that because God is One, Supreme, and has no rival or equal! There is thus no "devil" out there competing with Him.
Wrong. I've heard Satan twice. Smith Wigglesworth saw Satan once sitting in his bedroom, and he just turned over to sleep. So he exists. Also, I know a deliverance minster (among other things), who saw Satan, as a lion in her room, and he pounced her, and she could feel the fur against her cheek.
1 Peter 5:8
Be well balanced (temperate, sober of mind), be vigilant and cautious at all times; for that enemy of yours, the devil, roams around like a lion roaring [ in fierce hunger], seeking someone to seize upon and devour.
Further, "satan" merely refers to our own lower (animal) nature when we give it control instead of our higher (spiritual) nature.
That's unbiblical, so that's not true.
If you don't believe Satan exists, you also have to reject the story when Jesus was tempted by Satan in the desert. What you are saying is unbiblical, thus it's false.
Matthew 4:1
Then Jesus was led (guided) by the [Holy] Spirit into the wilderness (desert) to be tempted (tested and tried)
by the devil.
If you don't believe Satan exists, you have to reject hell exists. Jesus went there and proclaimed victory over Satan and lost souls, and that the Rich man went there.
Matthew 12:40
For even as Jonah was three days and three nights in the belly of the sea monster, so will the Son of Man be three days and three nights in the heart of the earth.
1 Peter 3:18-22
18 For Christ [the Messiah Himself] died for sins once [a]for all, the Righteous for the unrighteous (the Just for the unjust, the Innocent for the guilty), that He might bring us to God. In His human body He was put to death, but He was made alive in the spirit,
19 In which He went and preached to the spirits in prison,
20 [The souls of those] who long before in the days of Noah had been disobedient, when God’s patience waited during the building of the ark in which a few [people], actually eight in number, were saved through water.(A)
21 And baptism, which is a figure [of their deliverance], does now also save you [from inward questionings and fears], not by the removing of outward body filth [bathing], but by [providing you with] the answer of a good and clear conscience (inward cleanness and peace) before God [because you are demonstrating what you believe to be yours] through the resurrection of Jesus Christ.
22 [And He] has now entered into heaven and is at the right hand of God, with [all] angels and authorities and powers made subservient to Him.
The Rich Man:
Luke 16:23-25
23 And in Hades (the realm of the dead), being in torment, he lifted up his eyes and saw Abraham far away, and Lazarus in his bosom.
24 And he cried out and said, Father Abraham, have pity and mercy on me and send Lazarus to dip the tip of his finger in water and cool my tongue, for I am in anguish in this flame.
25 But Abraham said, Child, remember that you in your lifetime fully received [what is due you in] comforts and delights, and Lazarus in like manner the discomforts and distresses; but now he is comforted here and you are in anguish.
Also proves Abraham's God wasn't the God of the Qur'an who chose Muhammad.
Baha'i Faith: Baha'is are encouraged to investigate all religions, and to appreciate truth no matter where it is found.
Truth is not found in doctrines of demons like Qur'an has and Baha'u'llah, etc. I've already proven it by scripture that it's both Sinful and false.
