Jesus Predicted his Death and Resurrection

Matthew 16:21 (NIV) From that time on Jesus began to explain to his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, the chief priests and the teachers of the law, and that he must be killed and on the third day be raised to life. (see also Matt 17:22,23, 20:17-19, Mark 8:31-33, 9:30-37, 10:32-24, Luke 9:21,22, 44-50, 18:31-34, John 12:20-36)
"From that time on" -- and captured ten times in the four gospels! Jesus knew what awaited him, and it was clearly a focus of his teaching. But it appears that "The disciples did not understand any of this. Its meaning was hidden from them, and they did not know what he was talking about." (Luke 18:34 - see also Mark 9:32). How odd! The words themselves are easy to grasp. How could the meaning be "hidden"? Perhaps a deeper understanding is necessary to "get it." 

To help his disciples comprehend his  death and resurrection ,   Jesus followed with these words:
Matthew 16:24 (NIV) Then Jesus said to his disciples, “Whoever wants to be my disciple must deny himself and take up his cross and follow me. 25 For whoever wants to save his life will lose it, but whoever loses his life for me will find it. 26 What good will it be for someone to gain the whole world, yet forfeit his soul? (see also Matt 10:39, Mark 8:35, Luke 9:24, 17:33, John 12:25)
