It is not my argument.
I simply presented Scripture from both the Old and New Testaments as to the nature of God of whom we can say "God is love", He is also holy and wrathful against those who rebel against Him.
John 3:36 He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
And, no, I don't believe in some kind of futuristic divinely-ordained Holocaust; that is just one of many eschatologies which one can draw out of the Bible if one wants to to which I do not subscribe
Luke 17
24 For as the lightning, that lighteneth out of the one part under heaven, shineth unto the other part under heaven; so shall also the Son of man be in his day.
25 But first must he suffer many things, and be rejected of this generation.
26 And as it was in the days of Noe, so shall it be also in the days of the Son of man.
27 They did eat, they drank, they married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and destroyed them all.
28 Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded;
29 But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all.
Jesus compared His coming with two biblical events, one global the other local, both involved the wilful destruction of human life by God our father which is scriptural.
5 And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
6 And it repented the LORD that he had made man on the earth, and it grieved him at his heart.
7 And the LORD said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air;
Genesis 19
24 Then the LORD rained upon Sodom and upon Gomorrah brimstone and fire from the LORD out of heaven;
25 And he overthrew those cities, and all the plain, and all the inhabitants of the cities, and that which grew upon the ground.
