Nobody can know when World Peace will happen, and our human limitations seem to be in the way of it happening without some significant 'Divine help'. We must learn to accept others as they are; we must learn to forgive others for their mistakes; we must learn to be willing to "do unto others what we would not mind being done to ourselves". In fact, we must learn (if it is possible) to even love our 'enemies'; for only at that level of love is real peace possible.
We all want peace, right? So, let's brainstorm together to learn what we can do...individually and collectively...to help make some progress in the difficult journey toward that goal.
