Pure silica has a melting point of 3600F and while it can be made into glass for special applications, two other substances are always added to simplify processing. One is soda, or sodium carbonate, or potash, the equivalent potassium compound, which lowers the melting point to 1800F. However the soda makes the glass water-soluble, which is usually undesirable, so lime or calcium oxide is the third compound, added to restore insolubility. Soda-lime glasses account for about 90% of manufactured glass.
We have stood at the Indiana Glass factories, and watched the glass blowers with their long tubes, blowing the glass over a ever so hot fire. It looks so easy to form any kind of vase, plate, drinking glass, or anything else you desire.

Diamonds are made of the same stuff that coal and your pencil lead are made of--carbon, the atoms are just arranged in a way that makes the bonds very strong.
The bonds are made when carbon is at a very high temperature and under very high pressure. Under the earth at depths of 180km, there is a temperature of 1100 to 1400C. The high pressure is made by the weight of 180km of rock pressing down upon it.

Pearls are formed when an irritant, a grain of sand or a microscopic worm works its way into an oyster's shell. Over the years, the irritant is coated with concentric layers of calcium carbonate to form the pearl's nacre - the smooth surface which reflects light and glows with color.

Most of the time, in God's economy, real saints have had to go through times of fire, iritants, and pressure. The fire has been so hot, the iritants so annoying, and the pressure so very heavy. The saints have faced sickness, poverty, loss of family, loss of physical sight and on goes the list of maladys. Most of God's saints have had many things against them, most seemed unsurmountable.
Im thinking of Fanny Crosby, the hymn writer, who could not see with physical eyes, but had a very clear spiritual eye sight!
You are, right now, thinking of someone who has touched your life, who faced extreme odds, but overcame those to become God's pearl--a very smooth shiny pearl, that was a testimony of God's power!
You are also thinking of someone right now, whose inward heart was as black as coal, until people prayed. Maybe it was years of praying. Then, when the pressure was put on them by the Lord, they were transformed by His power from a lump of coal to a sparkly cyrstal clear diamond, glistening in the sunlight of God's love.
You see, without the flood, there wouldnt have been an ark. Without the water, there wouldnt have been a rescue of humanity.
You may go through some "high waters" and through some very hot "fires", but if you allow God to work, you will come out a shining saint, to the glory and praise of your Maker!
