In a recent debate between Bart Ehrman and Jimmy Akin, Bart claimed (in second 58:28 in this link https://www.youtube.com/watch?v=dKShBLRixR8&t=8137s ) that if we take the gospel narratives separately, we see that Jesus is shocked that He was crucified. He makes a point that this narrative in Mark is contradictory to the narratives in other gospels where Jesus is less silent and more deliberate about His crucifixion. 

However, is it true that Jesus was shocked with His predicament in the gospel of Mark? It is simply not true and a misrepresentation by Bart of the gospel of Mark.  

If we take references from the gospel of Mark alone, we find that Jesus clearly prophesied three times that He was going to be executed and resurrected from death. In Mark 8, right after Peter confessed Jesus as Christ, Jesus “began to teach them that the Son of Man must suffer many things, and be rejected by the elders and chief priests and scribes, and be killed, and after three days rise again. He spoke this word openly” (Mark 8:31-32). On a later occasion, in Mark 9, Jesus repeated His prophecy of His death and resurrection as “He taught His disciples and said to them, “The Son of Man is being betrayed into the hands of men, and they will kill Him. And after He is killed, He will rise the third day.” (Mark 9:31). For the third time, in Mark 10, Jesus predicts His death and resurrection even in more detail saying “Behold, we are going up to Jerusalem, and the Son of Man will be betrayed to the chief priests and to the scribes; and they will condemn Him to death and deliver Him to the Gentiles; 34 and they will mock Him, and scourge Him, and spit on Him, and kill Him. And the third day He will rise again” (Mark 10:33-34).
