Can this happen between God and humans? Absolutely. Just remember that He has more means of communication than humans (everything that exists, in fact).

A short list of what marks good, healthy dialogue: 

A back and forth rythm

Times when one does more listening than the other, according to the circumstance

Both ask deep, meaningful questions  

Both listen actively  

An appreciation for silence  

Knowing when the conversation is more important than the answer

A sincere interest in the other  

Authenticity (no pretense or avoidance of what's really going on) 


Give a thought to which of these you may employ with a bit more skill. We could all use some brushing up. (Bear in mind these are good ideas for the humans in your life, too!)
