As the Ruling Shepherd, Jesus will return to reward His under-shepherds who were faithful in their care of the flock (I Peter 2:25; 5:2, 4). The shepherd is the symbol of the king, and in this regard, it is interesting to note how many of Israel's kings, patriarchs, and prophets began as shepherds.
Jesus does not mix His metaphors when He exhorts His disciples, "Do not fear, little flock, for it is your Father's good pleasure to give you the kingdom" (Luke 12:32). Three figures of speech combine to form the ideal kingship familiar in ancient times: the perfect king was shepherd of his flock, the loving father of his family, and commanding ruler of his country. Thus, when Jesus says with authority, "I am the good Shepherd," the qualities of shepherd, parent, and ruler are seen combined in Him (John 10:11, 14).

Taken alone, these three verses could give us the impression that salvation is a free, downhill ride. However, II Peter 1:10 levels the playing field considerably in its sobering instruction: "Therefore, brethren, be even more diligent to make your calling and election sure, for if you do these things you will never stumble." If salvation is a free coast into the Kingdom, why does Peter admonish us to be diligent to make sure we do not fall? Paul adds that we have a responsibility to "work out [our] own salvation" (Philippians 2:12). These instructions do not contradict but complement and balance, making our responsibilities more specific and varied.

Jesus says, "I know My sheep, and am known by My own." Both the Shepherd and the sheep are aware of this, and it enables the Shepherd to lead His sheep in the best possible way, helping them to learn what He teaches and to do what He commands. Being known by and knowing the Shepherd implies that, not only do they know His voice, but they have an intimate understanding of the way He thinks and are inclined to reflect His way of doing things. Their imitation of the Shepherd becomes automatic because the sheep anticipate his will. They become one with the Shepherd, as the Shepherd is one with the Father (John 10:15, 30). Just as full knowledge exists between the Father and the Son, the Shepherd has a complete knowledge of each of His sheep.
