The viewpoint of where God is, depends upon so many factors, so that the answers that one is wont to receive will vary all over the place, to which, though, mainstream thought is often along the line that God is somewhat removed from planet earth, so that He is often pictured on a celestial throne, to which He may well send down to us, great souls and great prophets, but for the most part God is not pictured as walking amongst us. That's fine for what it is, but probably isn't the best way to view God and certainly isn't a very personal way to see God, to which humans have an innate need to picture God as something far more personal.
While there are certainly many passages in the Bible that speak of Heaven, of God, of ascending and descending, so too there is one very special passage: "Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you." (Luke 17:21). It is this scriptural passage which is so crucial for developing a different mindset, something that is of value to children and adults alike, which makes God much more personal, makes God much more tangible, and makes God much more real to us. The fact of the matter is when you believe that God is part and parcel of you, meaning that He is as close to you as a best friend could possibly be, never to leave you, you thereby make God much more meaningful for you and your subsequent behavior in this life.
There are few advantages of having a detached viewpoint of God, a sort of a disinterested God, who may or may not respond to our prayers in times of crisis or whenever, and is overall seen more like a gentle, slumbering giant, who takes a bit of pleading or plodding to get revved into action. That isn't God! In point of fact, God is always with us, each one of us, from the time of our conception, to the time of our physical death. God will never leave us, never forsake us, never to not love us, God is all that we could ever ask or desire for, and He is right here with us, right now. This is the truth of the matter, that each of us has God available to pick us up when we are down, to guide us through troubled times, to comfort us in times of sorrow, and to celebrate with us when we have done right.
The better understanding that God is always with us, allows us to have a more, meaningful relationship with God, so that rather than placing God on a pedestal to which we must continually bow down to Him in servitude and abject surrender, instead we see God as our greatest Friend, someone to trust and to open our hearts to, who will never forsake us and will always be there for us, no matter how events may transpire on a given day.
God should be our best friend, and this isn't meant to say that we should ignore nor not desire human company, as God is not here with us in human form, but rather we would all be better served to believe that God is imminent within us and that thereby "… If thou canst believe, all things are possible to him that believeth." (Mark 9:23)
