The Savior Knew His Life Before He Came Here

Today I read Psalms 20 - 22.  The first two were pretty similar to all the rest of the Psalms, praising God, promising defeat on the heads of the wicked and whatnot.  The last one however was about the life of the Savior.  It never fails to astonish me when I see Old Testament prophets correctly talking about the Saviors life and death.  It makes me just shake my head that so many prophets could correctly know the truth and understand it, and yet so many others, those that lived at the time of His life and death, would not understand and by their own lack of understanding and refusing to believe that they would kill their own Messiah, caused it to come to pass.  It is indeed a self fulfilling prophecy.  But of course the Savior knew what He was doing and what He was getting into from the start.  It makes me wonder, did we know and understand what our earthly lives would hold?  And if so, we still chose them?  That is bravery for some of us that have had truly horrible lives.  It shows that having a physical body is that necessary and important, more than so than we can understand it would seem.  Until tomorrow.
