Everywhere we look we see life blooming in nature or in the people around us. At the same time, everywhere we look is death. Without death we could not have the miracle of life, because with no life there is no death. If God did not allow suffering, that would mean that we would no longer have freedom to make choices. If God always made everyone do the right thing so that there is no suffering, we wouldn’t have the choice to make wrong decisions which means we then have no freedom.
