Following Paul’s explanation of the proper attitude toward each other regardless of the type of spiritual gift one attained (cf. 12:12-31), he begins his explanation of the purpose of said gifts (this explanation continues into chapter 14). Love takes precedence over all spiritual gifts, for without love the gifts bring no profit to the one who possesses them (cf. 13:1-3).
He furthers this explanation by mentioning the unfailing (everlasting) nature of love (cf. 13:8). This is in contrast to the spiritual gifts which will fail, cease, and vanish away (cf. 13:8). These gifts are “in part” (v. 9). They are contributing parts of a whole, or “that which is perfect” (v. 10). In order to understand the whole, we must understand the part.
These gifts were derived from “the same Spirit” (12:4). They were manifestations for the “profit of all” (12:7). Later, Paul discusses their purpose – edification through understanding (cf. 14:5, 9-12). This Spirit is that which is given that we might know the mind of Christ (cf. 2:6-16). The gifts are “part” of the revelation of God’s will! Paul explains that these will vanish away when “that which is perfect…” – the complete revelation of God’s will – “has come” (13:10)!
Their purpose is met in the infancy of the church (cf. 13:11). Until “that which is perfect has come” they will see “dimly” like looking into an ancient mirror. However, when the complete revelation comes they will see as clearly as other people see them in person (cf. 13:12). Unlike these spiritual gifts, faith, hope and love will abide even when “that which is perfect has come” (cf. 13:13). Love is greatest, for without it all else is without profit!
