νυνί; (νῦν with iota demonstrative (Krüger, § 25, 6, 4f; Kühner, § 180, e. (Jelf, § 160, e.); Alexander Buttmann (1873) Gram. § 80, 2)), in Attic note, at this very moment (precisely now, neither before nor after; Latinnunc ipsum), and only of Time, almost always with the present, very rarely with the future (cf. Lob. ad Phryn., p. 19). Not found in the N. T. except in the writings of Paul and in a few places in Acts and the Epistle to the Hebrews; and it differs here in no respect from the simple νῦν; cf. Fritzsche, Romans, i., p. 182; (Winer's Grammar, 23);

First Corinthians: A New Translation with Introduction and Commentary
By Joseph A. Fitzmyer
13. And now faith, hope, love remain, these three. So Paul draws his description of love to a close, with a verse that has many problems, not the least of which is the connection of the threesome to what has immediately preceded in vv. 10-12 and the addition of faith and hope to a discussion that has involved so far only love. It is a formula that is meant to terminate the discussion of love and its relation to the pneumatika, but it introduces a further discussion of two of them; and its wording raises a number of questions.
One thing is clear, however, pistis is not the same as that in v. 2, "faith to move mountains"; rather it now denotes the full sense of saving and justifying "faith," the response to the Christian gospel, as in other Pauline passages (Rom 10:6-10: belief in the death and resurrection of Christ Jesus), and especially in those in which the triad further occurs (l Thess 1:3; 5:8; Gal 5:5—6; cf. Col 1:4-5). Note also the linking of love to faith in 1 Cor 16:13-14; Thess 3:6; Phlm 5. The triad, however, is meant to replace the threesome of tongues, prophecy, and knowledge of vv. 1-2 and 8.
The first difficulty is the meaning of the adv. nyni, "now." It is scarcely to be understood as the equivalent of the temporal adv. arti (v. 12a), which was contrasted with tole, "then," another adv. of time. It is rather expressing a logical conclusion, as in Rom 7:17: “but now,” i.e., as the situation is (BDAC, 682). Cf. also il Cor 12:18; 15:20; 2 Cor 8:11, l2.
