For one who ponders over these events, there are countless lessons. In them there is proof of a second life after the present life. Similarly, there is a sure indication in them that He who has given things can also take them away. Then, there is the example of water. Reservoirs of water are mostly found here in the shape of seas containing salt water. About 98 percent of the water is found in seas and one tenth of its volume is made up of salt. It is a miracle of God’s law that when water vapour rises from the sea, pure water rises and the salt is left below. The fact is that the system of rain is a huge universal desalination process. Had this natural arrangement not been in place, all of the water in the world would have been brackish just like sea water. The snow on mountain peaks, the water flowing in rivers would all have been extremely salty. In spite of the vast stores of water on the earth, the non-availability of fresh water would have presented an insurmountable problem for humanity. If man gave this matter consideration, his heart would be full of praises for God.
