God speaks. Don't take that for granted. He is under no obligation to speak to us, but he does. He reveals himself to us by speaking in various ways but ultimately through Jesus. We are not left guessing about what God is like. We don't need to wonder how he would respond to people and situations because we can see how Jesus responded to them. God can and will speak to you today - look at the person of work of Jesus and hear him speak to you.
In the past God spoke to our ancestors through the prophets at many times and in various ways, but in these last days he has spoken to us by his SonHebrews 1:1-2
