When water is splattered on the table, you may notice it gather in puddles on the flat surface. It rises from the table in a liquid shell. And, like the raindrop above, it can hold against gravity.
Well, some may wondering how water can ever be “3D” when it is so . . . liquidy. We have talked about this briefly before, but the answer lies in cohesion and a thing we call surface tension.
Water, when it is in any form exposed to air, must create a surface area that conflicts with the air. The area between the water and the air is a thin strip of water molecules stuck together tightly, this area is called the surface tension of the water.
Now, the surface tension is created by a thing called cohesion. This is developed because water molecules bond together near the top. They are held together there by positive or negative “pulls”. These pulls push the water molecules together toward the surface whereas the other molecules, underneath the surface, are pulled and pushed so many ways, they cannot come together. The following illustration points it out well.
The ones on the surface get more support directed toward surface tension whereas the molecules below get their support pushed all over so that they can’t create surface tension.
It is worthy to note though, when the water molecules get colder, the bonds get stronger and the surface tension starts turning to ice. Then the area beneath it starts to turn into ice and so on and so forth until it is all ice.
It is an amazing process that keeps liquid (especially water) so important in our life. Without this bonding, water would not be able to hold together and we would die (unless we found a way to drink water molecule-by-molecule.
Anyway, although it is an amazing process, it is only the springboard for my message.
Christians are kind of like water molecules. They all bond with each other. They all bond differently. Some get their bonding stretched out far and wide while others keep the bonding close and narrow. But, it is the molecule that goes to the edge that is truly spectacular.
This guy gets the least support yet he holds together along with all the other molecules to hold the water together. This molecule is the one who goes forth and preaches the Gospel. He makes contact with the world, yet doesn’t go into the world. He stays in the drop, but he still makes contact.
This water molecule, however, cannot do it all on his own. Who will help him deliver the Gospel? Anyone?
