Here is a great quote from Karl Barth. I have cut this from an extended quote here.
"God with us! That is too strong a contradiction, not only over against our sins and sufferings but also against the nature of our existence down to the very deepest depths of its roots. God with us! That conflicts too much, not only with our unrighteousness, but more yet, with our righteousness; not only with the atrocities of history, but more yet with history's supposed progress and achievements; not only with the misery on earth, butmore yet, with the supposed happiness and saisfaction on earth. God with us! That subjects our total human nature to a judgment, to a No, that will leave nothing left of us, and will bow us under a grace, a Yes, that we cannot comprehend. God with us!
