Oh&we're not all his sheep?
Jesus says so himself.
Matthew 25
31 “When the Son of Man comes in his glory, and all the angels with him, he will sit on his glorious throne. 32 All the nations will be gathered before him,
and he will separate the people one from another as a shepherd separates the sheep from the goats. 33
He will put the sheep on his right and the goats on his left.
34 “Then the King will say to those on his right, ‘Come, you who are blessed by my Father; take your inheritance, the kingdom prepared for you since the creation of the world. 35 For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in, 36 I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me.’
Ever heard of the parable of Wheat and Tares?
So some of us were created by Satan? No.
I never said that. The bible says that humans are created by God, the Psalmist describes it as being "knit in my mothers womb".
limited atonement is blasphemy.
Is everyone atoned for?
If so, why is someone being treated as though their account is lacking, when it's been paid in full?
Let alone, Jesus says it himself.
John 10
11 “I am the good shepherd. The good shepherd lays down his life for the sheep.
