Please tell me, what must I do to be saved?
Your bitter grudge is not his way
What bitter grudge? Calling sin a sin? Jesus was more than a little upset by fornication.
Not withstanding I have a few things against thee, because thou sufferest that woman Jezebel, which calls herself a prophetess, to teach and to seduces my servants to commit fornication, and to eat things sacrificed to idols. And I gave her space to repent of her fornication; and she repented not. Behold I will cast her into a bed, and them that commit adultery with her into great tribulation, except they repent of their deeds. And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts; and I will give unto everyone of you according to your works.
That is my Lord who chastises those he loves, calling sin sin, and rewarding those who continue in sin accordingly. You should meet him. Read your Bible.
You do not define “fornication” for Yeshua.
Perhaps you embrace secular marriage as YHVH’s marriage, but there is no Biblical evidence to support that. Man’s laws do not override YHVH’s laws.
Jezebel has absolutely no relevence to this case, and you know it. This couple considered themselves to be one, and man’s law seeks to divide them.
Be careful, lest YHVH gives unto you according to your works.
