God is able to do "exceedingly abundantly" more than we could ask or even think, even when we're at our worst. Anytime I'm at church, I try to relate the message with something that I am going through... for instance, our struggle with trying to get pregnant. I know that God has a plan simply based upon this verse. He has something in store, more than I could even begin to imagine. There's a purpose behind it all - even when I don't see it, God is able.
I somehow managed to find a little piece of her sermon similar to what she spoke at the Radiant Conference. You have to watch it! It's only a minute long!
If you're feeling like you're in an impossible situation, just remember this verse and that God is able!
