Unfortunately, not taking a stand is in fact communicating something about your beliefs.
Here's what I believe:
Marriage was created by God and His definition of it stands (see Genesis 2:18-24).
Here's what I (Lord-willing!) will do:
I'm taking my crew of 7 to Chik-fil-a (though we typically do not eat processed foods simply b/c it's not good for us) to support them on August 1, Chik-fil-a Appreciation Day.
So, do you have plans on August 1st? If not, might I encourage you to eat some chicken?
