Its true that there is much suffering in this world.
Brahmakumaris consider the last days of the cycle to be Hell , where the sufferings would increase due to accumulation of sins since many births. God exhibits His greatest Mercy here that He extinguishes the heat of this Hell with the rain of His knowledge, paving way for a new spring , on a renewed Earth called Heaven , and we believe this is why He is worshiped , adored and hearts(souls) remember Him in times of need.
