His Coming was predicted even in the Garden of Eden: And for the next 4,000 years prophets foretold what He’d be like and where He’d be born
But, their eyes were blinded to His Arrival by
“the god of this world”
and their “hearts were hardened through an evil heart of unbelief and the deceitfulness of sin” (II Corinthians 4:4; Hebrews 3:12-13).
That’s why they didn’t recognize Him as the long-awaited, anointed-and-appointed, Promised Deliverer sent from God ( the Messiah/Christ): and ultimately rejected Him, refusing to accept Him (John 1:12).
And, that’s why He prayed “Father, forgive them: for they know not what they do” (Luke 23:24)— for, in reality, they didn’t know Who He was/is or they wouldn’t have nailed Him to the Cross.
