How Do You Know What God Wants You To Do?

I think that God is telling me to look for another job,” or “God wants me to buy this house instead of that one,” or “It’s God’s will that I be happy.” As Christians, we may have made statements like this and we would assume that anyone making these types of statements has some way to know what God wants for them. The real question is how do we really know? Is there a formula or a ritual or a feeling that shows us what God wants for us? You would think that if God is working with real and true Christians, then he would have a really clear way to show them what He wants. So, is there a really clear way for us to see God’s will?
