So God created man in his own image, in the image of God created he him; male and female created he them.
And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it. (Gen 1:27-28)
We have a powerful and sacred gift to create life, and it was entrusted to us by our loving Father in Heaven. In whose image we were created. One of the very first commandments given to us was to have children, to multiply and replenish the earth. This is a big deal, this is Gods very power of creation given to us. When used properly it can bring so much joy into our lives, but when used improperly it can lead to so much sorrow.
In the movie Jurassic Park a group of scientists try to create their own life. They clone dinosaurs for a theme park they are making and try to play God. They abuse the power of creation and it quickly leads to a dangerous situation that they were not prepared for. As a result of their toying with things they did not fully understand several scientists were killed by the dinosaurs they themselves made. While our choices may not lead to velociraptors eating Samuel L, Jackson, they may have serious consequences of their own.
"I was overwhelmed by the power of this place; but I made a mistake, too. I didn't have enough respect for that power and it's out now. The only thing that matters now are the people we love: Alan and Lex and Tim. John, they're out there where people are dying." -Dr. Ellie Sattler
This privilege that God gave to man is not something to be taken lightly, but that isn't to say that it's bad! Within the bonds of marriage and with a full understanding of the importance it has, the ability to bring souls into this life is a beautiful and holy thing. But outside the bonds of marriage and with no thought of the consequences of our actions it can ruin relationships and even lives.
Just don't forget whose power it is, and to treat sacred things like sacred things. Be chaste, and have a nice valentines day.
