Going but not knowing

There are so many articles in the web now on this topic. Perhaps there are millions of christians journeying in a similar way with some of us. When the Lord says go, we go but we do not have any idea where exactly. Sometimes we think that we can plan where we will be in the next 3 or 5 years, then go to this place and that place after that. But in reality, the journey goes on and on as the Lord directs us. We have lived a life that is so comfortable, the desire to be settled is just overwhelming, we plan our reirement home and so on, but will we really stop journeying?
