According to Jesus the Pharisees could not understand His words because they did not agree with his teaching. (John 8:43)
He also said they did not want to hear what He had to say because His words were different from their father's words (John 8:44).
God was His father but Satan was their father. Jesus would only do what the Father would do and they would only do what their father would do. They desired/lived to fulfill their lusts just like their father (John 8:44)
The word father means originator, head, chief or ruler. Satan the original sinner became god of this world and the father, originator, ruler or leader of all born in the flesh. (2 Corinthians 4:4) But God becomes the father of all those born of the spirit. (John 3:6) (2 Corinthians 5:17)
Choosing a "father'" began in the Garden of Eden.
God told Adam and Eve they would die if they ate from the tree of knowledge.(Genesis 2:17)
Satan told them they would not die if they ate from the tree. (Genesis 3:4) They believed Satan and ate from the tree, so we die!
So whose your father? Do you heed God's instructions/advice or Satan's both are always speaking.
Jesus taught the only valid reason for divorce was adultery. But their father "Satan" gave them permission to divorce their wives for any cause/reason. They divorced their wives for any reason, if she gained weight or if they found someone prettier.
Jesus taught his followers to honor their father and mother (Mark 7:10) (Luke 6:38). But their father taught them to take the money they should use to take care of their elderly parents and make a name for themselves by devoting it to the temple (Mark 7:11).
Satan's children used the political system to extort others but Jesus taught his followers to put God first instead of money thereby avoiding the temptation to oppress others for the sake of money. (Matthew 6:24)
Satan says Hell is not real, or if hell is real Jesus is to too good, loving and kind to send people there. But Jesus said, Hell is real and many will go there although it was not created for man but for Satan and his angels (Matthew 25:41).
We can't choose our biological father but God gives us the responsibility to choose who will be our spiritual father.
So take a look at your life, whose your father? Are you loving God and acknowledging Him in all your ways? (Proverbs 3:6)
Have you repented and accepted God's call of reconciliation? (2 Corinthians 5:18)
When we acknowledge Jesus Christ as our Lord and Savior we are adopted into God's family. We are transferred out of the kingdom/family of the dark one and transferred into the kingdom/family of light. (Colossians 1:13)
Will you join your father in hell or choose to join your father in heaven?
The choice is yours.
