yep, it works. you want examples?
my latest was today. yesterday a friend was telling about her hummingbirds that she has down in Texas. I've had hummers here, but hadn't seen evidence of a single one yet this year; 2 months after they should have been here.
I like them, and God knows that. today as i was looking out my window i saw a hummer who came to my flowers for a drink. Now that may be small to you, but to have a hummer show up at that exact moment that i was looking at the flowers that i had planted, in hopes that they would come---to me that's God working.
i don't think that there's any request too great or too small that God can't handle.
want another example? yesterday and this morning i was experiencing a bit of a sore throat. Nothing major, just a small nagging sore throat that i told God i didn't want. I went to church anyway, sang all the praise songs, and walked out of the church with no sore throat! A small thing, but nothing is too small for God.
now not only did He heal me from my sore throat, but He also gave me eyes to see and experience a new appreciation for my pastor's wife this morning.
God let me see her as a great woman that He worked thru for many years.
This morning we got to see the fruit of her many years of faith and devotion as she worked to raise her children, educate her husband, and support the growth of our church in so many ways, while always standing behind the scenes in a supportive role.
none of those things above could i have accomplished or made to happen on my own--it was all God doing every bit of that, just because He's good.
when most people think about asking God for things there's two mistakes that they make:
1. they only think to give Him the big stuff, and then only when there's no possible way that they can do anything about it themselves.
2. they fail to see the small things that God does for them out of His grace every day, just because He loves us and He cares for us.
