A Response to the Problem of Evil

Jeff Carter responds to my chapter on the problem of evil. He wrote:

Suffering allows for the proving and demonstration of courage, faith, stamina, perseverance, determination, spirit, triumph, glory, heroism, overcoming. Thus, while motives of an individual may be malicious, the condition of meaningless suffering is not evil to God - it is the backdrop against which the godly qualities of life are manifested and made clear.

My question is why these virtues are important to God since in heaven for the saints they will be completely irrelevant in an eternal bliss without any pain or suffering. See what you think.
