You completely ignored my post to you. What then do you make of Lucifer and Adam? Were they created by God with a design flaw?
No, I didn’t ignore your post - you are comparing apples to oranges. I don’t think it’s reasonable to compare our situation with Satan’s since he is a fallen angel, but neverless both Adam and Satan did have direct communion with God but were not indwelled by the Holy Spirit as a born again Christian is.
Ephesians 4:30 says “And do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption.”
The Holy Spirit seals a Christian just as the Bible says.
