You cannot take 1pet context and make it what you want in gen 6. clearly Jesus is the authority on the topic and HE said it was men. Your argument is with His words not mine.
Matthew 24: 37-39
As it was in the days of Noah, so it will be at the coming of the Son of Man.
38For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark;
39and they knew nothing about what would happen until the flood came and took them all away.
Now as far as 1pet 3 you again take one verse out of context to make fit what is not there.
lets reread it shall we starting at verse 18
18 For Christ also suffered once
for sins, the righteous for the unrighteous, to
bring you to God. He was put to death in the body but made alive in the Spirit. 19 After being made alive,[
d]
he went and made proclamation to the imprisoned spirits— 20
to those who were disobedient long ago when
God waited patiently in the days of Noah while the ark was being built. In it only a few people, eight in all,were saved through water, 21 and
this water symbolizes baptism that now saves you also—not the removal of dirt from the body but the pledge of a clear conscience toward God.[
e] It saves you by the resurrection of Jesus Christ, 22 who has gone into heaven and is at God’s right hand—with angels, authorities and powers in submission to him.
you take the word spirits from 1pet and make it angels ? yet it is not clear that is the case. why>?
1.So for you understanding to work Jesus had to die to save angels you cannot seperate that from 1pet 3
2. the spirits who were angels did not know who Jesus was whcih is speaking against the Eternal exsistance of Christ.
3. God had to wait for angels and wait patiently for an art to be built so save angels who would enter the Art if the repented?
Foolishness .
