Grace:
has various uses,
(
a) objective, that which bestows or occasions pleasure, delight, or causes favorable regard; it is applied, e.g., to beauty, or gracefulness of person,
Luk 2:40; act,
2Cr 8:6, or speech,
Luk 4:22, RV, "words of grace" (AV, "gracious words");
Col 4:6;
(
b) subjective,
(1) on the part of the bestower, the friendly disposition from which the kindly act proceeds, graciousness, loving-kindness, goodwill generally, e.g.,
Act 7:10; especially with reference to the Divine favor or "grace," e.g.,
Act 14:26; in this respect there is stress on its freeness and universality, its spontaneous character, as in the case of God's redemptive mercy, and the pleasure or joy He designs for the recipient; thus it is set in contrast with debt,
Rom 4:4,
16, with works,
Rom 11:6, and with law,
Jhn 1:17; see also, e.g.,
Rom 6:14,
15;
Gal 5:4;
(2) on the part of the receiver, a sense of the favor bestowed, a feeling of gratitude, e.g.,
Rom 6:17 ("thanks"); in this respect it sometimes signifies "to be thankful," e.g.,
Luk 17:9 ("doth he thank the servant?" lit., "hath he thanks to");
1Ti 1:12;
(
c) in another objective sense, the effect of "grace," the spiritual state of those who have experienced its exercise, whether
(1) a state of "grace," e.g.,
Rom 5:2;
1Pe 5:12;
2Pe 3:18, or
(2) a proof thereof in practical effects, deeds of "grace," e.g.,
1Cr 16:3, RV, "bounty" (AV, "liberality");
2Cr 8:6,
19 (in
2Cr 9:8 it means the sum of earthly blessings); the power and equipment for ministry, e.g.,
Rom 1:5;
12:6;
15:15;
1Cr 3:10;
Gal 2:9;
Eph 3:2,
7.
To be in favor with is to find "grace" with, e.g.,
Act 2:47; hence it appears in this sense at the beginning and the end of several Epistles, where the writer desires "grace" from God for the readers, e.g.,
Rom 1:7;
1Cr 1:3; in this respect it is connected with the imperative mood of the word
chairo, "to rejoice," a mode of greeting among Greeks, e.g.,
Act 15:23;
Jam 1:1 (marg.);
2Jo 1:10,
11, RV, "greeting" (AV, "God speed").
The fact that "grace" is received both from God the Father,
2Cr 1:12, and from Christ,
Gal 1:6;
Rom 5:15 (where both are mentioned), is a testimony to the deity of Christ. See also
2Th 1:12, where the phrase "according to the grace of our God and the Lord Jesus Christ" is to be taken with each of the preceding clauses, "in you," "and ye in Him."
In
Jam 4:6, "But He giveth more grace" (Greek, "a greater grace," RV, marg.), the statement is to be taken in connection with the preceding verse, which contains two remonstrating, rhetorical questions, "Think ye that the Scripture speaketh in vain?" and "Doth the Spirit (the Holy Spirit) which He made to dwell in us long unto envying?" (see the RV). The implied answer to each is "it cannot be so." Accordingly, if those who are acting so flagrantly, as if it were so, will listen to the Scripture instead of letting it speak in vain, and will act so that the Holy Spirit may have His way within, God will give even "a greater grace," namely, all that follows from humbleness and from turning away from the world.
See
BENEFIT,
BOUNTY,
LIBERALITY,
THANK.
Note: The corresponding verb
charitoo, "to endue with Divine favor or grace," is used in
Luk 1:28, "highly favored" (marg., "endued with grace") and
Eph 1:6, AV, "hath made... accepted;" RV, "freely bestowed" (marg., "enduced.").

Grace
Grace is unmerited favor.
Oswald Chambers adds that, "The gospel of the grace of God awakens an intense longing in human souls and an equally intense resentment, because the truth that it reveals is not palatable or easy to swallow. There is a certain
pride in people that causes them to give and give, but to come and accept a gift is another thing. I will give my life to
martyrdom; I will dedicate my life to service I will do anything. But do not humiliate me to the level of the most hell-deserving sinner and tell me that all I have to do is accept the gift of
salvation through
Jesus Christ."
[1]
The grace and
mercy of God strikes at the very heart of humanity. It has the ability to raise the most extreme emotions by, as Oswald Chambers says, humiliating those who want to add something to their salvation. On the other hand, it can spark emotions of humility where one will "consider everything a loss compared to the surpassing greatness of knowing Christ Jesus my Lord, for whose sake [we] have lost all things" and counting them as "rubbish" (Phil. 3:8). This very grace came/comes through
Jesus (John 1:17; Romans 5:15; 1 Corinthians 1:4; 2 Timothy 1:9), a sufficient grace (2 Corinthians 12:9) that is shown through the "redemption through his blood" and "forgiveness of sins" (Ephesians 1:7) and it is this grace by which we are justified (Titus 3:7) and saved (Ephesians 2:8).
Peter tells us to "set your hope fully on the grace to be given you when Jesus Christ is revealed" (1 Peter 1:13), for we worship the "God of all grace" (1 Peter 5:10). Lastly, because we are saved through the work and grace of Jesus, we may approach "the throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need" (Hebrews 4:16).
