A single pearl is quite valuable. You can't find them easily. As far as I know, they are hidden in shells, for which you have to dive. A lot of effort for the little ball. But obviously worth the effort. We also say from time to time, "He or she is a real pearl," expressing that this person is something very special that you have to be careful not to lose. John, who wrote Revelation, had in his vision at the end glimpses of the heavenly city that awaits us - and there are 12 gates, each of which - listen and be amazed - is made of a pearl. Unimaginable. In addition, the streets there are made of pure gold. What wealth there must be! And what splendor and glory. Could we be missing anything there? Hardly! How rich and abundant heaven is and what a perspective for us!
I wish you an extraordinary day!
