Internal Consistency between 1 Nephi 16:10 and Alma 37:43-46

The Liahona is first mentioned in verse 10, though not by that name. I can't help but think of the words of the prophets whenever I read the stories involving this "director" of "curious workmanship". It is simple and leads one straight to the promised land, but it only works according to faith. Compare Alma 37:43-46:

43 And now, my son, I would that ye should understand that these things are not without a shadow; for as our fathers were slothful to give heed to this compass (now these things were temporal) they did not prosper; even so it is with things which are spiritual.

44 For behold, it is as easy to give heed to the word of Christ, which will point to you a straight course to eternal bliss, as it was for our fathers to give heed to this compass, which would point unto them a straight course to the promised land.

45 And now I say, is there not a type in this thing? For just as surely as this director did bring our fathers, by following its course, to the promised land, shall the words of Christ, if we follow their course, carry us beyond this vale of sorrow into a far better land of promise.

46 O my son, do not let us be slothful because of the easiness of the way; for so was it with our fathers; for so was it prepared for them, that if they would look they might live; even so it is with us. The way is prepared, and if we will look we may live forever.
