What this guy >>814171 said, but also realize that God doesn't always speak to us with words. An example from my life that actually just happened over the past two days:
>sign up for marrow donation registry a year or two ago
>get call yesterday saying I'm a potential match
>on the fence now, it's one thing to say "yeah I'll help" and another entirely when you get that call
>unsure, I ask God to let me know what His will is for me
>today, get a call from the registry
>patient is no longer searching for a match
>I don't need to go forward with any more testing or anything
>my prayer was answered, and God didn't say a word
