If you read through the Bible you find that when God speaks things happen. Starting in Genesis we read that God spoke and the world was created. We read that God would flood the earth and He did. We read that God would confuse the language and He did. We read that God said Abraham and Sarah would have a child and they did. We read that the children of Israel would live in Egypt in slavery for 400 years and they did. We read that the older (Jacob and Esau) would serve the younger and he did. All of this and not only is this just the first book but this does not even cover it all.
It happens time and time again in the Bible that God speaks and things happen. Now we can get all excited and jump up and down about when God speaks for what we want to happen and we can call on God to speak in our favor but that is not the only type of speaking God does. We know how to handle that kind of speaking because we want that kind of speaking but can we be as excited and obedient when God speaks in other ways?
Sometimes God speaks and says no. Sometimes God speaks and tells us what we do not want to hear. David wanted to build a temple and God said no. That was still God speaking and it still happened the way God wanted. God spoke to Moses and told him he would not enter the promised land and that is how it happened. Both men obeyed and thankfully the outcome was good. But there are examples of God speaking and saying no to something but people not listening. Honestly, about half the Old Testament is the prophets telling Israel no or recounting the stories of their failures. God was still speaking in those situations.
Other times God speaks and says not now. He delays promise fulfillments and says there will be a delay because He is God. These are still examples of God speaking and the outcome is still as God says.
The truth is that God speaks and things happen but He is not always saying yes. In Isaiah 55:11 God says through Isaiah that His word does not return void but accomplishes what He sent it to do. We have to be as willing to receive the no and not yet as we are the yes.
It is the same as when God speaks about what will happen or answers prayer, He gives direction and calls us to something. In the Gospels, we read that Jesus called the disciples and they followed. We read that Jesus called Saul who was a persecutor of the church and he followed. We read that Paul (formerly Saul) had a thorn in the flesh and when he prayed for it to be removed God said no. That was still God speaking and Paul chose to listen.
My question to you and to me is do we listen we God says no or not yet. Are we willing to listen even when the answer is not what we want? One of my favorite biblical examples of this is Jerimiah 42 and 43. In chapter 42 the people come to Jerimiah and say ask God what we should do and we will do it. In chapter 43 they reject what Jerimiah says. They said they wanted to hear from God but what they wanted was to hear what they wanted. It is a dangerous game asking for God to speak because He might not tell us what we want to hear. The question is this: Are we willing to listen and obey?
