30 Therefore having overlooked the times of ignorance, God is now declaring to men that all people everywhere should repent, 31 because He has fixed a day in which He will judge the world in righteousness through a Man whom He has appointed, having furnished proof to all men by raising Him from the dead."
Since the ressurection of our Lord Jesus, God has been declaring to all people everywhere that they are to repent, because a day of judgment is coming. He has fixed a day for the redeemed as well as those who reject the Gospel.
The spoken word to the world in this age, is to repent before the fixed day, and God waits patiently not wanting any to perish.
Only the Father knows the day or hour.
Elsewhere, regarding the righteous judgment,
When he comes he will render to every man, (rev 22)
he will raise and change and rapture the sheep the last day, (Jn 6 , 1thess 4),
and his already spoken word will judge all the last day. (Jn 12).
God the Father has fixed a day when he will send Jesus to seperate his flock from the goats.(Matt 25)
Rom 2- shows clearly a fixed day that includes both the righteous and unrepentant.
But do you suppose this, O man, when you pass judgment on those who practice such things and do the same yourself, that you will escape the judgment of God? 4 Or do you think lightly of the riches of His kindness and tolerance and patience, not knowing that the kindness of God leads you to repentance? 5 But because of your stubbornness and unrepentant heart you are storing up wrath for yourself in the day of wrath and revelation of the righteous judgment of God, 6 who will render to each person according to his deeds: 7 to those who by perseverance in doing good seek for glory and honor and immortality, eternal life; 8 but to those who are selfishly ambitious and do not obey the truth, but obey unrighteousness, wrath and indignation.
I have fought the good fight, I have finished the course, I have kept the faith; 8 in the future there is laid up for me the crown of righteousness, which the Lord, the righteous Judge, will award to me on that day; and not only to me, but also to all who have loved His appearing.
Paul includes himself in the day God has fixed, when the righteous judge returns to resurrect and award him his reward.
To summarise the fixed day -;
The Son coming to judge the world in righteousness,
on the last (fixed) day.
2Thess 1 sums it up.
This is a plain indication of God’s righteous judgment so that you will be considered worthy of the kingdom of God, for which indeed you are suffering. 6 For after all it is only just for God to repay with affliction those who afflict you, 7 and to give relief to you who are afflicted and to us as well when the Lord Jesus will be revealed from heaven with His mighty angels in flaming fire, 8 dealing out retribution to those who do not know God and to those who do not obey the gospel of our Lord Jesus. 9 These will pay the penalty of eternal destruction, away from the presence of the Lord and from the glory of His power, 10 when He comes to be glorified in His saints on that day, and to be marveled at among all who have believed—for our testimony to you was believed.
The testimony that is believed is the spoken word to repent...before the fixed day.
All who have ever believed will be glorified on this day of righteous judgment and the opening of the book of life.
Has God fixed a couple of days where he will judge the world in righteousness by sending his Son?
