I believe that the Trinitarians will win even if the Trinity were not true. The Trinity is of course true, but assuming only that it is wrong, I would say that Trinitarians will still go to paradise. For what does the Father want to say? Does he really want to say to a Trinitarian at the end, "Wait, you believed that my only begotten Son and my Spirit are God as I am? You wicked man! To hell with you!" Never would he say that. He would love it if someone honored his beloved son and spirit like that. But what about Unitarians? If the Trinity is true, then it is a very serious sin not to believe in it, because you would be denying God His deity. Jesus himself said, "If you do not believe that I am He, you will die in your sins"
Very interesting concept.
It is difficult for one to understand the Lord, if one has a faulty concept of him.
Jesus said, “The first of all the commandments is ‘Hear, O Israel, the Lord our God, the Lord is one; therefore you are to love the Lord your God with all your heart and with all your soul.’” (Mark 12:29, 30)
Hear, O Israel, Jehovah our God is one Jehovah; you are to love Jehovah your God with all your heart and with all your soul. (Deuteronomy 6:4, 5)
Someone came to Jesus and said, “Good Teacher, what good thing should I do in order to have eternal life?” Jesus said to him, “Why do you call me good? No one is good except the one God.” (Matthew 19:16, 17)
. . . so that all the kingdoms of the earth may acknowledge that you alone are Jehovah. (Isaiah 37:20)
I am Jehovah and there is no other. There is no God other than me. [I have prepared you] so that people will know from the rising of the sun to its setting that there is no God other than me. I am Jehovah and there is no other. (Isaiah 45:5, 6)
Jehovah Sabaoth, God of Israel, dwelling between the angel guardians, you alone are God over all the kingdoms of the earth. (Isaiah 37:16)
Is there any God other than me? Or any other Rock? I do not know of one. (Isaiah 44:8)
Who is God, except Jehovah? Who is the Rock, if it is not our God? (Psalms 18:31)
