Judgment in the Bible is extremely controversial for reasons that need not delay us here. The noun "judgement" actually translates several different Greek words:
Krino: This verb denotes the act of separating or deciding, judging. It occurs 8 times in Revelation (6:10, 11:18, 16:5, 18:8, 20, 19:2, 11, 20:12, 13) and 106 times in the rest of the New Testament.
Krisis: This noun denotes the investigation or court trial, the judgement process, the process of collecting evidence, preceding the final decision. The word is often used to refer to the end-time judgement in the phrase, “day of judgement”, that is the eschatological cosmic trial in which all matters will be resolved (Matt 10:15, 11:22, 24, 12:36, 41, 42, Luke 10:14, 11:31, 32, 2 Peter 3:9, Jude 6). Since a trial is a neutral process, this can refer to justice (Matt 12 18, 20, 23:23, Luke 11:42, Acts 8:33) or condemnation (Matt 23:23, John 5:24, 25, James 5:12, Rev 18:10).
The intensive form, katakrisis, literally means the process (or evidence) leading to condemnation (2 Cor 3:9, 7:3). In just one instance, this word for trial is used in the sense of verdict when one might have expected krima (John 3:19).
Krima: A noun which denotes the act of deciding following the process above; it is translated decision, verdict, sentence, condemnation, punishment, and judgement. However, in almost all cases, the most suitable translation would be verdict or sentence (Mark 12:40, Luke 23:40, 24:20, Rom 2:2, 3, 3:8, 11;33, 13;2, Gal 5:10, 1 Tim 3:6, 5:12).
The intensive form, katakrima, literally means a strong condemnation or severe sentence (Rom 5:16, 18, 8:1).
In the specific case of Rom 2:16 we have:
in the day when God will judge [κρίνω verb] the secrets of men by
Jesus Christ, according to my gospel.”
This judging by God refers to the great eschatological judgement (see appendix below). The righteous earnestly seek the judgement of God for a variety of reasons:
- It is associated with the second coming of Jesus
- it is a time when all wrongs will be corrected and the saints vindicated
- Dan 7:22 - until the Ancient of Days arrived and pronounced judgment in favor of the saints of the Most High, and the time came for them to possess the kingdom.
- Rev 6:10 - And they were crying in a loud voice, saying, "Until when, O Lord, holy and true, do You not judge and avenge our blood from those dwelling upon the earth?"
- Luke 18:1-8 - the parable of the importunate widow illustrates that the righteous earnestly seek judgement to have justice
- Ps 19:9 - The fear of the LORD is pure, enduring forever; the judgments of the LORD are true, being altogether righteous.
- Ps 119:39 - Turn away the disgrace I dread, for Your judgments are good.
- Judgement described in Matt 25:21-46 where the righteous have this said of them: "*Come, you who are blessed by My Father, inherit the kingdom prepared for you from the foundation of the world. ... *"
The best way to illustrate this is the reaction of the two classes of people when they see Jesus return "in the clouds of heaven"
- Righteous: Isa 25:9 - And in that day it will be said, “Surely this is our God; we have waited for Him, and He has saved us. This is the LORD for whom we have waited. Let us rejoice and be glad in His salvation.”
- Wicked: Rev 6:15-17 - Then the kings of the earth, the nobles, the commanders, the rich, the mighty, and every slave and free man hid in the caves and among the rocks of the mountains. And they said to the mountains and the rocks, “Fall on us and hide us from the face of the One seated on the throne, and from the wrath of the Lamb. For the great day of Their wrath has come, and who is able to withstand it?”
Thus, it is not surprising that the Gospel contains good news about the (eschatological) judgement of God.
APPENDIX - Judgments in the Bible
In “The New Unger's Bible Dictionary”, we also have a list a several judgments. According to Unger, an inductive study of the Scriptures shows that there's more than one general judgement (with which I broadly agree) and goes as far as to specify eight distinct judgement described in the Bible
- Judgement of the Cross - This is the judgement upon sin effected by Christ when He said "It is finished" (John 19:30). It is the basis of the believer’s salvation when he believes. Christ has borne the sinner’s guilt and in Him, as a substitute for all on behalf of whom He died, sin has been judged. The one who believes on Christ has been released from judgment, and “there is therefore now no condemnation” (John 5:24; Rom. 8:1; Gal. 3:13; Heb. 9:26– 28; 1 Pet. 2:24).
- Judgement of Believers - This takes the form of divine correction and chastisement (1 Cor. 11:30-32; Heb 12:3-13; John 15:1-9). The apostle Paul says: “But if we judged ourselves rightly, we should not be judged. But when we are judged, we are disciplined by the Lord in order that we may not be condemned along with the world” (1 Cor. 11:31–32). This, then, involves God’s disciplinary action against a sinning saint. “The sin leading to death” (1 John 5:16; cf. 1 Cor. 5:1–5; Acts 5:1–11) occurs when the believer, through deliberate continued sin, brings reproach upon the name of Christ and upon his salvation by free grace, and forfeits his physical life “that his spirit may be saved in the day of the Lord Jesus.”
- Believer's Works - This judgement concerns only Christians and it is not a matter of judgement for sins that have been judged at the cross and with which the believer will not again be faced (John 5:24; Rom. 8:1); it involves instead the divine appraisal of the Christian’s works and service. This will entail reward or loss of reward (2 Cor. 5:10; Rom. 14:10, 12; Eph. 6:8; 2 Tim. 4:8).
- Judgement of Self - This is referred to in 1 Cor. 11:31-32. It has reference to stern criticism of a Christian of his own ways with accommodation to the divine will and immediate confession of and turning away from all sin (1 John 1:7–9). True confession is equivalent to self-judgment and involves immediate cleansing and restoration to fellowship and walking “in the light.”
- Judgement of the Nations - This judgement is referred to in Matt. 25:31-46. It involves divine dealing with the nations on the basis of their treatment of Israel. The “goat” nations on the left hand involve those peoples who are sent to the lake of fire. The “sheep” nations on the right hand enter the millennial kingdom. The peculiar basis of this judgment is the way all nations have dealt with Israel during the Tribulation period preceding the second advent of Christ. OT prophecy is clear in its prediction that some Gentile nations will enter the coming kingdom of Israel (cf. Isa. 60:3; 61:6; 62:2). These nations will be subordinate to Israel. As the millennial state merges into the eternal state, Gentile nations are still asserted to be on the earth when the heavenly Jerusalem descends from heaven (Rev. 21:24, 26).
- Judgement of Israel - Ezekiel 20:33-44 clearly teaches that Israel must come into judgement before being restored in the millennial kingdom. This OT teaching has confirmation in the NT from the parable of the ten virgins (Matt. 25:1–13 (see Joel 3:11–15). Prophecy seems to teach that there will be a general resurrection of all truly regenerated Israelites of the past dispensation to be judged. Those who had a kingdom hope are to arise and enter the earthly glory (cf. Ezek. 37:1–14; Dan. 12:1–3).
- Judgement of Angels - These are fallen angels and are evidently judged in connection with the great white throne (1 Cor. 6:3; 2 Pet. 2:4; Jude 1:6).
- White Throne Judgement - This last great judgement comprehends the judgement of all unsaved of all ages (Rev. 20:11-15). The basis will be works, which evidently suggests differences and degrees of punishment. All who are not found in “the book of life” are cast into “the lake of fire.” This is called “the second death,” which means final and complete cutting off from God’s presence and a sin-cleansed universe. [The other side of this judgement is the righteous are vindicated by the same process.]
To this list, Unger might have added one more:
- Judgement of God – this is the doctrine of Theodicy – where everyone is to judge whether God has been just or otherwise and is mentioned several times in places such as Rom 3:4 (“when You are judged”), Rev 14:7 (the judgement of God), Rev 16:4-6 where people declare God to be righteous and just. See also Ezra 9:15, Ps 51:4, 119:33, Neh 9:33, etc.
