Son Light!

The Laws of Thermodynamics was the subject of our third Backyard Science Club. I must be very honest in telling you that I only understand the very simplest explanation of Thermodynamics. And so I will share with you as I did my BYSC kids the little I retained enough to re-teach!

Thermodynamics is the study of how energy works in a system.

A thermodynamic system is one that interacts and exchanges energy with the area around it. At least one way must be the transfer of heat. Heat is a form of energy!

The first law of Thermodynamics explains that when heat is added to a system, some of that energy stays in the system and some leaves the system.

For example if you heat a pot of water on the stove energy has been added to the system. But some of the energy (heat) will also be added to the air around the stove.

The second law of thermodynamics explains that it is impossible to convert 100% of the energy added to a system into work. Some amount of energy in a reaction is always lost to heat that escapes the system. []

If you have very cold hands and rub them together they warm up. This heat is caused by friction, but your hands, the system, cannot contain 100% of this heat some is lost into the area or air around your hands.

Very basically speaking whenever work is gained some energy is also lost.

The sun in our solar system is responsible for much of our available energy here on earth.

“God’s creation of the sun not only provided the world with light; it also gave heat and energy to the earth. Most energy people use is derived from the sun. Gas for cars, coal for heat, and oil for electrical energy all come from “fossil fuel”, which is sunlight energy stored in ancient plants. Even wood that burns in the fireplace comes from the sunlight energy the tree stored as it grew…the sun’s energy can [also] be used directly by solar power stations.” [And God Created Science: Exploring Outer Space, 30 Amazing Projects that Explore the Wonders of God’s Creation, Stephanie Finke, Promise Press, imprint of Barbour Publishing, Inc. ©2000]

God did indeed create our sun. He did so that we might have light and heat. Without our sun we could not survive.

Then God said, “Let there be light,” and there was light. ~ Genesis 1:3

God also has provided us with spiritual light – Jesus the Son of God.

Jesus spoke to the people once more and said, “I am the light of the world. If you follow me, you won’t have to walk in darkness, because you will have the light that leads to life.” ~ John 8:12

Jesus told him, “I am the way, the truth, and the life. No one can come to the Father except through me. ~ John 14:6

Jesus the Son of God is very much like the sun in our universe. He gives of himself that we might have light to live by and a way to eternal life with the Father. The sun gives of its energy to make the work of heat and power that helps us survive here on earth. Jesus put his very life into the system of redemption and created the work of salvation. What He lost by his death and resurrection became our gain of eternal life.

But he gave up his place with God and made himself nothing. He was born as a man and became like a servant. And when he was living as a man, he humbled himself and was fully obedient to God, even when that caused his death—death on a cross. ~ Philippians 2:7-8 NCV

Jesus was given to die for our sins, and he was raised from the dead to make us right with God. ~ Romans 4:25

Thermodynamics can be complicated to understand and so is redemption for some of us. How could the God of the universe be willing to put his own son into a system that would cost him so very much? The answer can only be his great love for us. Just as he created a sun to help us live physically he was compelled to create a system that would produce a work of forgiveness that we might be able to live spiritually as well.

You light a lamp for me. The LORD, my God, lights up my darkness. ~ Psalm 18:28 NLT

Show me today Lord how to live in your light!
Help me to accept your work of salvation!
