Hello! I see this question very often, and it’s a good one! There are a lot of different ways a God can talk to you, and often these are very personal. But here are several ways I’ve experienced or heard of:
– You feel a very close connection with Them, even without legitimate reason. Some people feel a connection to Their area of rule (i.e. sea god for feeling close to the ocean). If you’re like me, you’ve felt drawn to a God and you don’t even know why (Hades for me). This could be the Gods trying to reach out to you.
– A God sends you strong gut feelings. Before I devoteed to Hades, I gave Him offerings during every Sabbat. I can’t tell you why; I just felt like I needed to. One day, I thought of making an altar for Hades, and I immediately put aside all other thoughts and responsibilities, determined to create that altar. If you’ve experience similar gut feelings, that may be a God speaking to you.
– Your favorites overlap. It sounds silly, but it’s an experience I’ve heard about from a lot of people. For example, if you’ve always felt connected to dogs, and feel drawn towards Aries, you might look up the correspondence of dogs and realize that Aries has a close relationship with dogs.
– Your environment responds to you when you speak with the Gods. During my first ever Wiccan ritual, the God spoke to me by raising the candle flame higher than any I’ve ever seen. I’ve felt the wind shift when I spoke to the Gods about change in my life. This experience often happens during prayer or ritual.
– You feel a response, similar to the last one, but more esoteric. Examples may include feeling a warm blanket on your shoulders, feeling yourself relax while speaking to the Gods, or even smelling a certain scent from no obvious source.
– You hear a response. In some cases you may actually hear a voice in your head when a God speaks to you.
These are just some examples. Listen to your instinct and you’ll know. It may take some time.
As for speaking to the Gods, there are many ways: talk out loud to Them, write to Them in a journal, give offerings, go out into nature and simply listen. If you don’t hear an immediate response, keep trying! Sometimes the Gods wait for the right time, or are testing your devotion towards Them.
I hope this helps, lovely! I wish you a rewarding path!
