You can't always get the whole image in focus. There is only one plane in the image that is "in focus". In front of and behind that plane the image can be "acceptably" in focus due to depth of field, the amount of which depends upon the aperture you're using.
The focus indicator light in the viewfinder will indicate proper focus when manually focusing.
