A summary of what I've been trying to say all these blogging years:
We do what we can and let God do the rest. We let the Lord know everything and get him involved in everything. This shows that we trust in him. Basically, we let the Lord take over and we help him on the side, you might say, to accomplish his will. You no longer worry about anything, since you just follow. This is absolutely the way to live. But if you have trouble letting go, it's not for you yet. Seek to attain union with God (taking the fast track), then you'll be there.
