Salt, poison, explosions, and marriage

Salt is a very simple thing. It sits on the dinner table and you put it on fries and potatoes. It makes the gives the food more taste and is a well liked thing in our country. The origins of salt are actually quite dangerous though. To make salt you combine, sodium and chloride. Originally sodium by itself is explosive and chloride is poisonous. And we eat it every day!
God created sodium and chloride to make salt. God also created man and wife. God made man at the beginning of time and he created woman as a companion for him. They were to live together with all the animals of the garden and had only one rule. They were companion to each other in marriage just as sodium and chloride are companions to each other to in salt.
God created both salt and marriage but both have their impurities. God created it perfect but because of our sinful nature we bring in the impurities and now we need to ask Him to take away the impurities. An example of an impurity in marriage is unfaithfulness.
I saw a movie once about devotion called "Fireproof" and in the movie there was a man who was having trouble with his marriage. He had a friend who gave him an example with that where he glued the salt and the pepper shakers together to show how marriage was something that was supposed to unite people and not destroy the people involved.
The salt and pepper shakers stayed together even with all their impurities with the help of glue. Humans need to stay together even with all their impurities with the help of God.
