From New Testament Institute Manual--Mark 6  

The feeding of the five thousand is one of the only miracles besides the Resurrection that is found in all four Gospels. Elder Jeffrey R. Holland of the Quorum of the Twelve Apostles identified an eternal truth we learn from this miracle: “Don’t worry about Christ running out of ability to help you. His grace is sufficient. That is the spiritual, eternal lesson of the feeding of the 5,000” (Trusting Jesus [2003], 73).

Similarly, Elder J. Devn Cornish of the Seventy taught that the feeding of the five thousand is one of the scriptural accounts that “can teach us symbolically of the power and abundance of the Savior’s atoning grace. … His grace is truly abundant and more than sufficient to meet all our needs” (“Learning How the Atonement Can Change You,” Ensign, Apr. 2002, 23). This truth can be appreciated by noticing the sequence of statements and actions:

1. The Savior gave a commandment beyond the disciples’ present ability: “Give ye them to eat” (Mark 6:37). The impossibility of this task is reflected in the disciples’ response, found only in Mark. They said that the amount of bread needed to feed such a multitude would have been “two hundred pennyworth,” or two hundred denarii—roughly eight months’ wages for a common laborer.
2. The Savior asked the disciples what they could provide: “How many loaves have ye?” (Mark 6:38). The disciples told the Savior they had found five loaves and two fishes.
3. The Savior instructed, “Bring them hither to me” (Matthew 14:18).
4. The disciples gave the Savior what they had.
5. The Savior blessed and multiplied what the disciples were able to provide, miraculously meeting and surpassing what was needed.

This sequence mirrors a pattern in our relationship with the Savior. On our own, we fall far short of the perfection and glory of God (see Matthew 5:48; Romans 3:23). But when we offer our whole souls to the Savior, the abundant power and grace of His Atonement will more than compensate for our shortcomings (see 2 Nephi 25:23; Omni 1:26; Moroni 10:32–33).

President James E. Faust (1920–2007) of the First Presidency taught that the Savior’s power to multiply the loaves and fishes shows that He will magnify our faithful efforts to serve in His Church, even if we feel that our efforts are equal to only a few loaves and fishes:

“Many nameless people with gifts equal only to five loaves and two small fishes magnify their callings [in the Church] and serve without attention or recognition, feeding literally thousands. … These are the hundreds of thousands of leaders and teachers in all of the auxiliaries and priesthood quorums, the home teachers, the Relief Society visiting teachers. These are the many humble bishops in the Church, some without formal training, but greatly magnified, always learning, with a humble desire to serve the Lord and the people of their wards. …

“A major reason this church has grown from its humble beginnings to its current strength is the faithfulness and devotion of millions of humble and devoted people who have only five loaves and two small fishes to offer in the service of the Master” (“Five Loaves and Two Fishes,”Ensign, May 1994, 5–6).
