God's Goals or Safe Goals?

I recently stumbled upon a missions project to raise some funds for a special item. The item had no specific price tag, but would fund various ministries. The goal was x-amount of dollars. I thought, well that shouldn't be too hard. When my wife and I looked at it together, we both thought something new-- this was a typo. They had left off a zero.
They hadn't. They had a nice little safe goal. I'm not saying that it wasn't bathed in prayer, but it was certainly obtainable. God didn't even need to roll up a sleeve, or break a sweat, to accomplish this one.
We're in the process of converting our office to a nursery, out with the office, and in with the pink baby stuff. I stumbled on a treasure cache of stuff, lot's of trash, lot's of recycling and dust behind the bookcases (who would think you have to remove books and dust behind them). I came across a missions magazine which had an article from a pastor. Small church, average attendance 200, missions-hearted. They heard of a need for a Missionary hospital in Africa. They began to raise money and within a year, they had $50,000. They didn't want to hold on to the money, but get it there for the missions work, so they sent it and during the process found out the total cost was $100,000. They decided they would raise the rest. Within the next year, they did it -- God did it. God flexed His muscle and through His people He gets the glory.
God raised the $100,000 through His people, for His work. The church's regular giving and tithing never dropped off, they paid all their bills all the way through.

Do we pick safe goals, that we can obtain, God doesn't need to be bothered with this? Or do we let God direct what the goal should be, so that He can roll up His sleeves and flex His might, so that He gets all the glory for what was accomplished.

I get goosebumps when God starts flexing His muscles.
