A couple of snippets from 1 John 5.

[14] And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:[15] And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.

What I'm learning is that if God wants something done, He'll work it out if I trust Him enough to allow Him to. What I still wonder about is how to trust God with the things I'm not sure He wants. It's hard to step out in faith and expect God to come through when you're not convinced His plan is the path you've chosen.

[19] And we know that we are of God, and the whole world lieth in wickedness.

This, to me, is a good definition of the world. Not "anything that's outside of explicit Christianity", but wickedness. Something is worldly if it's wicked, not if it's something that worldly (wicked) people do, because they often do plenty of good things.
