“And we did magnify our office unto the Lord” said Jacob concerning his brother and him. What does that mean? Gordon B. Hinkley compared that to a pair of binoculars. You look in one side, it makes what you see bigger. Look in the other side and things shrink. So, if you magnify your calling, you are showing that you need to do it. But flip the binoculars around and you are diminishing your calling and acting like it is not important.
