The OT. In the OT the experience and expression of joy are close, as the terms for joy (usually smh) and its expression show. Joy expresses the whole person and aims at sharing, as in festal joy. God's work of salvation is a chief occasion (Psa_5:11; Psa_9:2; Psa_16:9, etc.).
The law is an object in Psa_119:14, the word of God in Jer_15:16. Joy is a reward for faithfulness to the law in Isa_65:13-14. There is joy at weddings (Jer_25:10) and at harvest (Isa_9:2). God himself rejoices (Isa_65:19), and thanksgiving demands joy (Deu_16:13 ff.). Feasts offer occasions for joy before God (Deu_2:7).
Hymnal jubilation expresses devotion to God (Joe_2:21). In accordance with its inner intention, OT joy culminates in eschatology (Psa_14:7; Psa_126:2; Isa_9:2; Isa_12:6, etc.). High points in the prophets carry the call: chaire (Zep_3:14 ff.; Joe_2:21 ff.; Zec_9:9-10).
C. Judaism.
1. Qumran. At Qumran we find the OT motifs of joy in God, of God's own joy, and of eschatological joy. The elect can rejoice in spite of present suffering because they know that they are in God's hand.
2. Rabbinic Writings. Here, too, we find festal joy, which God gives and into which it is a duty to enter. Joy is joy before God. The meal is part of the joyful festival. A significant thought is that of perfect future joy.
3. Philo. The group is a significant one in Philo. He relates joy to religious "intoxication." Joy is a supreme "good mood." It is the opposite of fear. Isaac is its OT symbol. God is the giver of joy, and its objects are health, freedom, honor, the good, the beautiful, and worship. While joy is a "good mood" Philo does not view it in Stoic fashion as a self-achieved harmony of soul. Joy is native to God alone; we find it only in God. It comes with virtue and wisdom. But this is possible only on the presupposition that by way of the logos God himself is the giver.
D. The NT.
1. Usage. In the NT chairo is the secular term and agalliaomai the religious term, but the two may be synonymous (cf. Rev_19:7), and they are associated, e.g., in Mat_5:12; 1Pe_4:13. The participle means "full of joy" in Luk_19:6. Various constructions are used, e.g., accusative, dative, epi with dative, dia with accusative, en, hoti, and participle. The greeting with chairein occurs only in Act_15:23; Act_23:26; Jas_1:1. The greeting chaire (Mar_15:18; Mat_26:49; Mat_27:29; Joh_19:3) may mean "rejoice" rather than "greetings" in Luk_1:28, where kecharitomene ("favored one") gives it special significance. The meanings of both verb and noun are to be sought in the contexts in which they are used.
2. The Synoptics and 1 Peter. The group is common only in Luke, which refers to joy at finding what is lost (15:5ff.), at one's name being written in heaven (10:20), at the coming of the Savior (1:14), and at the acts of Jesus (13:17).
The mood of the people is one of joy in 18:43, as is that of the disciples after the ascension in 24:52. There is joy at epiphany in Mat_2:10. Even trials are an occasion of joy (Jas_1:2). Suffering is a testing of faith (1Pe_1:6-7) with a christological basis (2:20ff.; 4:12ff.). One should not just rejoice "in" suffering but "at" suffering (Act_5:41). Already in Mat_5:11-12 Jesus forges a link between joy and persecution. The hope of future glory adds an eschatological dimension in 1Pe_4:12 ff. Heb_10:32 ff. presents another version of the same tradition that one should suffer with joy for faith's sake and with the hope of imminent deliverance.
3. The Pauline Corpus.
a. For Paul chara is the joy of faith (Php_1:25) and a fruit of the Spirit (Gal_5:22). God's kingdom is joy (Rom_14:17). Joy and hope are related (Rom_12:12). Its opposite is affliction (cf. Rom_5:1 ff.). Joy actualizes freedom and takes shape in fellowship (12:15). Paul wants to come with joy (15:32). Joy is reciprocal (Php_2:28-29). Joy is in God (1Th_3:9) or in the Lord (Php_3:1). In the relation between Paul and the church, joy is eschatological; the church will be his joy (1Th_2:19). The mood of Philippians is one of joy (1:4). This is joy at the preaching of Christ (1:18). It is future joy experienced as joy in the present (4:1). As the joy of faith it includes a readiness for martyrdom (1:25). This joy maintains itself in face of affliction (2Co_7:4 ff.). Paul himself, like the Lord, is an example in this regard (1Th_1:6). Paul's apostolic authority works for the joy of the church (2Co_1:24). He rejoices in his own weakness when it means the church's strength (13:9).
b. There is nothing new in later works. chairo occurs in Col_1:24; Col_2:5, and chara in Col_1:11; 2Ti_1:4. The most important aspect is that of joy in suffering.
