My dad builds houses, and sells them as part of his job. Today, he found a piece of land for sale that he might want to buy. It seems to me that he should buy it right now. He asked me what I thought, and I just said that I didn't really know what was best. Maybe God would say no, and we wouldn't understand.
What do these two stories have in common? We may think that we know best, but who knows if God will say no, because He knows way more than we do. Our job is to trust and obey.
