Jesus teaches that if Jews abide in His Word they will know the truth and the truth will set them free. Free from sin. He told those who would not accept Him that they were of their father, the devil, the father of all lies.
The Jews thought that they were God's special chosen ones. What does Jesus call them and why?
Who does Jesus say that He is? Why does this make the Jews want to stone Him?
How could it be that Abraham (who lived several thousand years before Jesus) could "see my day and was glad."
