Well, do you want a wife? Do you want anything that’s right and proper? You go to work, and you use the agency and power and ability that God has given you. You use every faculty, you get all the judgment that you can centered on the problem, you make up your own mind, and then, to be sure that you don’t err, you counsel with the Lord. You talk it over. You say, “This is what I think; what do you think?” And if you get the calm, sweet surety that comes only from the Holy Spirit, you know you’ve reached the right conclusion; but if there’s anxiety and uncertainty in your heart, then you’d better start over, because the Lord’s hand is not in it, and you’re not getting the ratifying seal that, as a member of the Church who has the gift of the Holy Ghost, you are entitled to receive.
