Satan is Gods Son.

God says we are all the children of the most high ...

Psalms 82:6 I have said, You are gods; and all of you are children of the most High.

That therefore includes Satan who Jesus says fathered the tares ...

Matthew 13:38 The field is the world; the good seed are the children of the kingdom; but the tares are the children of the wicked one; (39) The enemy that sowed them is the devil; the harvest is the end of the world; and the reapers are the angels.

The bible backs this up ...

Job 2:1 Again there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them to present himself before the LORD.

God does not turn Satan away and neither does not deny he is his son!

In-fact this is what happens to Satan ...

2 Corinthians 11:14 And no marvel; for Satan himself is transformed into an angel of light. [15] Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
