While I can appreciate where you're trying to come from, I wouldn't be so quick to make such an all-encompassing statement. Jesus said, "The thief comes only to steal and kill and destroy; I have come that they may have life, and have it to the full." There's a duality here (the now/then tension) in that Jesus brings the fullness of life both here and in the next life.

This doesn't preclude suffering, though, which I agree is a central tenant of Christianity. I would argue the primary role of suffering, from the Christian view, is to bring about conformity to Christ in this life.
