What do Jesus’ words, “not one” sparrow shall “fall on the ground without your Father” mean?

Question:

What is the meaning of Jesus’ words that “not one” sparrow shall “fall on the ground without your Father”;? Surely God has greater work to do than observing sparrows.

Answer:

This illustration shows how small the objects that receive God’s special concern may be, if worthy. “His eye is on the sparrow” is a figure of speech for His concern for any object of His love, however small. It is not to say that God observes sparrows, but that He watches those persons that He is shaping to receive His eternal love and blessing. In other passages of Scripture these persons are the “apple of his eye,” his own “prized possession,” his “jewels,” and his own “sons and daughters” (see Zech. 2:8; Ex. 19:5-6; Mal. 3:16-17; 2 Cor 6:17-18).
