One of the greatest possible sins would be to return to God the life which he has given us with our abilities undiscovered and our talents undeveloped an unutilized. One of Jesus most bitter rebukes was given to him who buried his talents in the ground.
When in our minds we pre-live our marriage, we help to determine the kind of person that we would like to be when that event arrives. As we pre-live our success, we develop the abilities necessary to bring it about. And with the information and direction given us in the Holy Scriptures we can even pre-live that important period that lies beyond the boundaries of this life.
Building a successful life is much like building anything else: it should be thoroughly thought about in advance and then carried through to completion.
