So they were saying to Him, "Who are You?" Jesus said to them, "What have I been saying to you from the beginning? ~ John 8:25
The Jews were willfully ignorant because chapters 1-8 demonstrate that multiple witnesses testified to Jesus' identity, and Jesus Himself in words and actions persistently proved throughout His ministry on earth that He was the Son of God and Messiah. – John MacArthur
Just before verse 25 Jesus once again said who He was. Sometimes when speaking to people they just don’t seem to get it or they don’t want to get it. And even now the people that say that Jesus is not God don’t seem to or don’t want to get it, even when it states Jesus is God over and over in the Bible. It is very frustrating when this happens. Do any of you ever seem to have this happen to you? Just curious.
