It is very happy thing that we are to be people who have a dream and accomplish it, but even though there is very good dream on earth, it is disappeared like a mist that appears for a little while and then vanishes. It"s because all men are like grass, and all their glory is like the flowers of the field; the grass withers and the flowers fall. Let me have a eample, person who has even honor, wealth, authority has only 70 or 80 years for his life. If he dies, what is used?
Therefore, God tells "What good will it be for a man if he gains the whole world, yet forfeits his soul? Or what can a man give in exchange for his soul?" to people looking at earthly life and living in it and encourages them who have a dream for eternal blessing and pleasure and trys to accomplish them.
