Suffering and Jesus

I'm sure there is an answer to this... i just couldn't think of it today.

While slaving around Hunters Hill my mind wandered to the answer i give to the problem of suffering (because i think my answer should feel as scripted and rehearsed as possible). A part of my answer includes the incarnation and how Jesus can sympathise with our sufferings (a true point).

But i wondered how this fits with the omniscience of God. If He knows all (which is true), wouldn't he already know what suffering felt like? He suffered when humanity turned away from Him prior to God breaking into human history two thousand years ago. Furthermore, He gave us the emotions that we feel when we do inevitably suffer.

All this hasn't changed the answer the answer i give to suffering, but i may wonder internally how it all exactly fits together. Deuteronomy 29:29 i guess...
