REWARD
Term that, although sometimes used of retribution for evil (Ps. 91:8; Abd. 15), is more generally used of something that is given in recognition of satisfactory behavior for the giver.
Future rewards for Christians are frequently discussed in the NT. Addressing His own, the Lord announces: “Behold, I am coming quickly, and My reward is with Me, to reward each one according to his work” (Rev. 22:12).
He who dedicates himself to the service of the Lord, if his work continues, will receive a reward (1 Cor. 3: 8, 14; cf. 2 Jn. 8).
The reward, although an encouragement, should not be the reason for the Christian’s action, for he must be able to say from the heart: “For the love of Christ constrains us” (2 Cor. 5:14).
The believer is exhorted not to be deprived of his reward (Col. 2:18; cf. 3:23, 24; Rev. 3:11). Eternal salvation should not be confused with rewards, however.
Salvation is not a reward, but a gift of pure grace (cf. Eph. 2:8, 9). The reward is given to each believer based on the works he has done in faithfulness to the Lord (Eph. 2:10).
At the judgment seat of Christ (2 Cor. 5:10) they will be evaluated, and the reward will be given for the construction that each one has carried out (1 Cor. 3:10-14).
If a believer’s work is unworthy of reward, he will lose it, but nevertheless he will be saved, on the ground of Christ’s work, of pure grace (1 Cor. 3:14-15).
