But when he saw many of the Pharisees and Sadducees coming for baptism, he said to them, “You brood of vipers, who warned you to flee from the wrath to come? Therefore bear fruit in keeping with repentance; and do not suppose that you can say to yourselves, ‘We have Abraham for our father’; for I say to you that from these stones God is able to raise up children to Abraham. The axe is already laid at the root of the trees; therefore every tree that does not bear good fruit is cut down and thrown into the fire. “As for me, I baptize you with water for repentance, but He who is coming after me is mightier than I, and I am not fit to remove His sandals; He will baptize you with the Holy Spirit and fire. His winnowing fork is in His hand, and He will thoroughly clear His threshing floor; and He will gather His wheat into the barn, but He will burn up the chaff with unquenchable fire.” Matthew 3:7–12, NASB
In the passage above John the Baptist was addressing a form of spiritual blindness that was afflicting the Pharisees and Sadducees. Is there the same sort of stubborn blindness pertaining to Christianity? Yes, sadly there is. Spiritual blindness is a darkness beyond our ability to describe. This blindness is rampant in the “visible Church” in our day. Jesus prophesied about this.
