If the devil and his angels commited sin by trying to overthrow God's throne,how did sin creep into heaven?

'Sin didn't creep into heaven'(it was ousted from heaven along with Satan). However, freewill and choice did!

Newsflash:

None of that ever happened. Those stories are just products of the imaginations of pre-bronze age goat herders.

Response to Chrysostom:

Sin did not, and connect, "creep into" heaven.

(Those who deny the supernatural limit the possibility of life beyond the natural, which denies the possibility of anything above themselves, thus making themselves gods - the ultimate hubris.)

Lucifer and his followers were led by the lust for power. God gave all the angels and lucifer free will just like us. and the Followers of Lucifer were blinded by greed and power. now heaven is for those who know that he is almighty and will worship him and no other. Sin "crept" into heaven before humans were there and it was explelled from it emediatly. now God watches over the gate to protect his followers.
