1 Corinthians 13:13
13. And now—Translate, "But now." "In this present state" [HENDERSON]. Or, "now" does not express time, but opposition, as in 1Co 5:11, "the case being so" [GROTIUS]; whereas it is the case that the three gifts, "prophecy," "tongues," and "knowledge" (cited as specimens of the whole class of gifts) "fail" (1Co 13:8), there abide permanently only these three—faith, hope, charity. In one sense faith and hope shall be done away, faith being superseded by sight, and hope by actual fruition (Ro 8:24; 2Co 5:7); and charity, or love, alone never faileth (1Co 13:8). But in another sense, "faith and hope," as well as "charity," ABIDE; namely, after the extraordinary gifts have ceased; for those three are necessary and sufficient for salvation at all times, whereas the extraordinary gifts are not at all so; compare the use of "abide," 1Co 3:14. Charity, or love, is connected specially with the Holy Spirit, who is the bond of the loving union between the brethren (Ro 15:30; Col 1:8). Faith is towards God. Hope is in behalf of ourselves. Charity is love to God creating in us love towards our neighbor. In an unbeliever there is more or less of the three opposites—unbelief, despair, hatred. Even hereafter faith in the sense of trust in God "abideth"; also "hope," in relation to ever new joys in prospect, and at the anticipation of ever increasing blessedness, sure never to be disappointed. But love alone in every sense "abideth"; it is therefore "the greatest" of the three, as also because it presupposes "faith," which without "love" and its consequent "works" is dead (Ga 5:6; Jas 2:17, 20).
but—rather, "and"; as there is not so strong opposition between charity and the other two, faith and hope, which like it also "abide." 1 Thessalonians 5:8
8. Faith, hope, and love, are the three pre-eminent graces (1Th 1:3; 1Co 13:13). We must not only be awake and sober, but also armed; not only watchful, but also guarded. The armor here is only defensive; in Eph 6:13-17, also offensive. Here, therefore, the reference is to the Christian means of being guarded against being surprised by the day of the Lord as a thief in the night. The helmet and breastplate defend the two vital parts, the head and the heart respectively. "With head and heart right, the whole man is right" [EDMUNDS]. The head needs to be kept from error, the heart from sin. For "the breastplate of righteousness," Eph 6:14, we have here "the breastplate of faith and love"; for the righteousness which is imputed to man for justification, is "faith working by love" (Ro 4:3, 22-24; Ga 5:6). "Faith," as the motive within, and "love," exhibited in outward acts, constitute the perfection of righteousness. In Eph 6:17 the helmet is "salvation"; here, "the hope of salvation." In one aspect "salvation" is a present possession (Joh 3:36; 5:24; 1Jo 5:13); in another, it is a matter of "hope" (Ro 8:24, 25). Our Head primarily wore the "breastplate of righteousness" and "helmet of salvation," that we might, by union with Him, receive both.
