This is a post-Christian world now, simply because so many Christians no longer even observe the basic tenets of their faith. Many Christians are turning away from their religion and finding other religions to follow, yet the ones who become followers of the Brit Noah or who convert to Judaism are fulfilling the words of Zechariah and Jeremiah:
Thus saith the L-rd of Hosts: In those days it shall come to pass, that ten men shall take hold, out of all the languages of the nations, shall even take hold of the skirt of him that is a Jew, saying: 'We will go with you, for we have heard that G-d is with you.' (Zechariah 8:23)
O L-rd, my strength, and my stronghold, and my refuge, in the day of affliction, unto Thee shall the nations come from the ends of the earth, and shall say: 'Our fathers have inherited nought but lies, vanity and things wherein there is no profit.' Shall a man make unto himself gods, and they are no gods? Therefore, behold, I will cause them to know, this once will I cause them to know My hand and My might; and they shall know that My Name is the L-rd. (Jeremiah 16: 19-20)
I say this as a Noahide and mean no disrespect to the Christian religion. I merely see the waning influence of Christianity, the rise of cultism, and the acceptance of the Unity of G-d by non-Jews as a "sign of the times". Many expect the Day of Wrath to arrive, yet I think that it will be unlike anything that anyone is expecting- simply because there are so many expectations about it! There are many, many earnest Christians who want to do what is right by G-d, who fear His Name, and who pray for the World to Come.
To wit, many
liberal Christians have forgotten the Name of the L-rd and profess strange doctrines, the worship of false gods, and an acceptance of the abominations of abortion and buggery. I speak not of the Christian Trinity, for that is a matter that is internal to Christianity (and many of the aforesaid liberal Christians deny the most cardinal aspect of Christian theology: the resurrection), but of accepting Allah as the equal of the L-rd or of accepting the Arab imposter as a greater prophet than Moses.
All of these acceptances of non-Biblical ideals is an affront to G-d and constitutes avodah zerah, yet many Christians have no trouble in seeing their activities as being entirely consistent with what G-d accepts from a believer. Actually, it is an opinion, their own opinion, of what G-d accepts and nothing more.
