A big part of this chapter is the dialogue between Jesus and the religious leaders. The chasm between them was becoming greater. They struggled to understand that being a descendant of Abraham was a matter of faith, not biology. They were also blind to their own sin and how sin had enslaved them.
We can struggle and the same things today. We can become convinced that our relationship with God is okay merely because we were raised in a Christian home, or we regularly attend worship, or we tithe our income, or we have held may positions in the church, or we have a certificate of baptism. We can also become blind to our own sin and how our sin enslaves us.
Jesus’ challenge to those who would listen was to make room in their hearts for His message. In this season, do we have room for Jesus?
John 8:31-34 NLT
Jesus said to the people who believed in him, “You are truly my disciples if you remain faithful to my teachings.  And you will know the truth, and the truth will set you free.”  “But we are descendants of Abraham,” they said. “We have never been slaves to anyone. What do you mean, ‘You will be set free’?”
 Jesus replied, “I tell you the truth, everyone who sins is a slave of sin.
