We cannot be happy if we only get to be happy for a short time. All things of the world pass, so there is no point in attaching yourself to any of them. I think of the tsunami that hit Japan suddenly 7 years ago which destroyed so many lives, homes, and buildings. Recently, the whole town of Paradise just 80 miles north of here burned to the ground and practically all the residents became homeless in no time. If we ever have another world war, the extent of destruction of lives and properties would be impossible to estimate. Therefore, get yourself detached from all things of the world and seek eternal security and happiness in heaven, then you'll be truly happy now and forever. No "here today, gone tomorrow"; we demand "here today and here forever"!
