Faith When You Don't Understand

I have had a "Faith" key for quite some time, honestly fully intending to wear it forever since I like it, and I am truly a person of faith. Despite knowing the intent of "giving keys", I never really thought about giving it away. However, my son-in-law's father was killed in a plane crash last week and we are heading to the funeral in the U.S. (I am from Canada). I'll be giving my key to my son-in-law's mom. She is obviously crushed by her husband's death, and I hope she'll find some comfort in my key. It's a small token, but I hope it will provide her some strength in the difficult, days, weeks, and months ahead...
