Some callings in the Church are coveted; others are feared. Whether one accepts a calling or not is ultimately a private matter between one and the Lord. But to suggest that it is a matter of personal preference ignores two important facts:
1. The Lord rarely issues the calling himself. Instead, he goes through one of his servants on earth—be they a prophet, bishop, or Relief Society president.
2. The Lord has given examples in the scriptures of how to act when called to do something that seems impossible.
I believe there are many scriptures that address this issue, but none better than 1 Kings 17:9-16. Elijah has been sent to Zarephath, in modern-day Lebanon, to be cared for by a widow. The widow, whose name remains unknown, has been "commanded…to sustain [Elijah]" by the Lord (1 Kings 17:9). Unfortunately, we have no record of how or when she received this commandment.
As we follow the narrative, we immediately see a problem:
10 So he arose and went to Zarephath. And when he came to the gate of the city, behold, the widow woman was there gathering of sticks: and he called to her, and said,
Fetch me, I pray thee, a little water in a vessel, that I may drink.
11 And as she was going to fetch it, he called to her, and said,
Bring me, I pray thee, a morsel of bread in thine hand.
Due to a curse on the land by the hand of Elijah, there was a severe drought, and we can assume that this contributed to the impoverished state of the widow and her son.
12 And she said,
As the LORD thy God liveth, I have not a cake, but an handful of meal in a barrel, and a little oil in a cruse: and, behold, I am gathering two sticks, that I may go in and dress it for me and my son, that we may eat it, and die.
What a heartbreaking reply from this poor widow! Not only would it be a sacrifice for her to feed Elijah, it would be the ultimate sacrifice. In her answer we find a noble example: she does not ask for pity, nor does she ask to be released from Elijah’s request. She simply and plainly tells the prophet the facts as she sees them.
This makes Elijah’s response seem all the more demanding:
13 And Elijah said unto her,
Fear not; go and do as thou hast said: but make me thereof a little cake first, and bring it unto me, and after make for thee and for thy son.
With her heart already beaten down by her situation and her inability to provide for her son, we can only imagine how hard these words were to hear. "I have nothing," she said, only to hear the charge, "Then give even that." Elijah’s command, however, is not without hope: she said there was enough meal for one cake only, yet in saying, "after make for thee and for thy son," Elijah hints that there will be enough for at least three. Indeed, Elijah promises much more:
14 For thus saith the LORD God of Israel, The barrel of meal shall not waste, neither shall the cruse of oil fail, until the day that the LORD sendeth rain upon the earth.
What an uplifting—and yet, seemingly impossible—promise in the face of such a demoralizing request! It is in this moment, in the way that she responds, that we learn the most from this faithful widow:
15 And she went and did according to the saying of Elijah: and she, and he, and her house, did eat many days.
Those three words—"went and did"—tell us everything we needed to know about this woman. Furthermore, they tell us everything we need to know about what the Lord expects when he issues a calling, "whether by [his] own voice or by the voice of [his] servants" (D&C 1:38). The widow did not refuse, but she did not immediately agree to something she felt incapable of doing either (see Mosiah 4:27 and D&C 10:4). Instead, she informed Elijah of her abilities and concerns, then left it up to him to retract or to repeat his demand.
The closing sentence does more than just give us a happy ending, it emphasizes the major themes of the story: first, that the Lord is faithful to those who are faithful, even to fulfilling all of his promises (Alma 37:17); and second, that those promises are made by the Lord through his servants.
16 And the barrel of meal wasted not, neither did the cruse of oil fail, according to the word of the LORD, which he spake by Elijah.
