Because He keeps throwing it in our laps. Facebook posts, news reports, friends, books, blogs, complete strangers - each and every one of them, without knowing it, confirms that the Lord is leading us towards something very hard, very scary, and very life changing.
I don't know details. I don't know when or where or how, but I do know that if He's so clearly leading us towards *this* then we'd better follow. I know that if He's asking us to trust and obey, that He will also be there to guide us. I know that it's probably going to be the hardest thing we've ever done, and that there are going to be days when I wish I could go back in time, but I also know that He who calls us, is faithful.
“If we desire our faith to be strengthened, we should not shrink from opportunities where our faith may be tried, and therefore, through trial, be strengthened.” ― George Mueller
