Yes, it is. it's having faith in the messiah, whom Jesus is/was.
Just because they did not know his name yet,. doesn't mean they didn't know the Messiah was coming.
Exactly! Psalm 110: 1 — “The LORD says to my lord: “Sit at my right hand until I make your enemies a footstool for your feet.”
But many had faith in the Messiah and rejected that Jesus was the Messiah. If you are saying God gave the benefit of the doubt to those before Jesus’ time then it sounds like you believe in invincible ignorance.
