Following His resurrection, the disciples could now understand and "believe" that the Old Testament Scriptures were actually fulfilled in the sacrificial and resurrection role of the Messiah (John 2:22).

Even soon after His resurrection, there was confusion concerning what was to really take place (John 20:9).

They "knew not" (John 20:9) the exact role of His mission, whether Jesus would be the military Messiah or the dying Messiah, who would rise again. They "knew not" the real timing of the Lord's program. It was difficult for them to piece the entire picture together about Christ's death and resurrection along with His coming kingdom.
