to exult: to break out in loud, exuberant joy, above all at what God has done
This is rejoicing with the volume turned up. Greek-speaking Jews seem to have built the word to carry the loudest joy of the Hebrew Psalms, the joy that whirls in a dance (גִּיל) or rings out in a shout (רָנַן), and the New Testament writers inherited it from them. So it does not describe a quiet good mood. It describes joy that shows: sung, shouted, danced, or leapt.
In the New Testament it belongs to the great moments of rescue, and the same word covers all of these:
- Mary's spirit exults in God her Savior
- Jesus exults in the Holy Spirit as his Father reveals himself to the childlike
- Abraham exulted at the prospect of seeing Christ's day
- a jailer in Philippi exults with his whole household once he has come to faith
- the church is summoned to exult at the wedding feast of the Lamb
Its most striking use is under pressure. Peter tells Christians who are being slandered and tested that they are exulting right now, and Jesus tells the persecuted to be glad out loud, because of what is coming to them. That is why this word carries a joy that does not wait for circumstances to improve: it is the joy of the end already spilling backward into the present.
One passage is quieter than the rest. In John 5:35 the crowds "were willing to rejoice for a while" in the light John the Baptist shed, a passing enthusiasm rather than worship, which shows that even a word trained for festival can relax into ordinary gladness.
Nuances
Whether the exulting of 1 Peter 1:6 and 1:8 is a joy the readers already have in the middle of their trials, or a joy still to come at the revealing of Christ.
- majorityThe present tense is meant: the joy of the last day has already begun and has transformed the readers' present suffering.; P. Achtemeier, 1 Peter (Hermeneia; Fortress, 1996), 100-101; J. H. Elliott, 1 Peter (AYB 37B; Yale, 2000), 338-342; K. Jobes, 1 Peter (BECNT; Baker, 2005), 92-95; J. R. Michaels, 1 Peter (WBC 49; Word, 1988), 27-29
- minorityThe verbs should be read with future reference, as most interpreters before Calvin took them, since grief and this kind of joy were held to be incompatible states.; T. W. Martin, "The Present Indicative in the Eschatological Statements of 1 Peter 1:6, 8," JBL 111 (1992): 307-312
Whether the exulting of 1 Peter 1:8 (with 1:6) is a joy the readers already have while unable to see Christ, or a joy still to come at his revealing.
- majorityThe readers exult now: unseen love and faith already yield a glory-laden joy in the present.; P. Achtemeier, 1 Peter (Hermeneia; Fortress, 1996), 100-101; J. H. Elliott, 1 Peter (AYB 37B; Yale, 2000), 338-342; R. Feldmeier, The First Letter of Peter (Baylor, ET 2008), 67-69
- minorityThe present forms carry future reference, so the joy belongs to the revealing of Christ rather than to the readers' present grief.; T. W. Martin, "The Present Indicative in the Eschatological Statements of 1 Peter 1:6, 8," JBL 111 (1992): 307-312
Disputed
Whether this word always names a heightened, festal, end-time joy distinct from the ordinary Greek word for rejoicing, or whether that content should not be read into every occurrence.
- majorityIt is a specifically religious word for intense, outwardly expressed, festal exultation, more demonstrative than the general word for joy, with its center of gravity in God's decisive saving act.; BDAG (Danker, ed.), A Greek-English Lexicon of the New Testament, 3rd ed. (2000), s.v. ἀγαλλιάομαι; J. P. Louw and E. A. Nida, Greek-English Lexicon of the New Testament Based on Semantic Domains (1988), 25.133; R. Bultmann, "ἀγαλλιάομαι, ἀγαλλίασις," in Theological Dictionary of the New Testament (TDNT) 1:19-20; C. Spicq, Theological Lexicon of the New Testament (TLNT), vol. 1, s.v.
- minoritySuch content cannot be assumed in every instance: the word is regularly coordinated with the general word for joy, which is at least as consistent with near synonymy, and John 5:35 is plainly ordinary.; J. Barr, The Semantics of Biblical Language (Oxford, 1961); M. Silva, ed., New International Dictionary of New Testament Theology and Exegesis (NIDNTTE), vol. 1, s.v.; N. K.
