THE three great "days" of Scripture, as shown on the
    chart of THE DIVINE CALENDAR,
    are Man's Day, the Day of the Lord, and the Day of God. Originally, in planning the chart,
    other days were noted, but, for simplicity's sake, they were later omitted, as the time
    they indicated was already included in the Day of the Lord. These are the day of the
    Son of Mankind (Luke 17:24), the day of our Lord Jesus Christ (1 Cor.1:8), the
    day of the Lord Jesus (1 Cor.5:5; 2 Cor.1:14), the day of Jesus Christ
    (Phil.1:6), and the day of Christ (Phil.1:10; 2:16). In designing the CALENDAR, I
    was inclined to make four days, giving the day of Christ a separate period
    between the end of Man's Day and the Day of the Lord, coinciding with the era of
    indignation which ushers in Jehovah's Day.
    In order to do this, it was necessary to take the apocalyptic judgments out of
    Jehovah's day and commence it with the manifestation of Christ in glory. But this was
    clearly wrong, for the revelations given to John, as well as to the prophets, begin that
    day with the fearful judgment period which immediately follows Man's Day. It was therefore
    necessary to reconsider the prevalent teaching as to the day of Christ, in the light of
    the passages in which this phrase occurs. If it is confined to the judgment period, it
    must coincide with the beginning of the day of the Lord. But, since it is not a distinct
    time from that day, there is no longer the need of limiting it to its commencement. It may
    be possible to allow it its natural meaning--the day in which Christ is supreme. This
    includes all of the day of Jehovah.
    THE DAY OF THE SON OF MANKIND
    The other phrases are also to be found within the bounds of this day. The days of the
    Son of Mankind are to be like the days of Noah. Hence the "day" includes the
    opening phase of Jehovah's day, and there is no good reason for withdrawing it while He,
    as the Son of Mankind, rules over all of Adam's race during the thousand years.
    THE DAY OF CHRIST
    The phrase "the day of Christ" occurs only in Paul's epistle to the
    Philippians (1:10; 2:16). This letter is especially occupied with the conduct which
    becomes us who have received the transcendent grace which is ours today. Hence we may
    hastily infer that the day of Christ is especially occupied with the judgment of our
    works. But the title used speaks of position rather than service. It speaks of the day of
    His official glory, when He is recognized as the Anointed, the Prophet like Moses, the
    great Priest after the order of Melchisedec, the King of kings. What has our conduct to do
    with that day! Very much indeed.
    It will be no great feat to be faithful and flawless in the glory, when He is acclaimed
    by all. His greatest glory then will not be found in the homage and obedience accorded Him
    at that time, but in that which comes to Him through His suffering saints in the days of
    His humiliation. In Israel this is clear. Those who have suffered reign. He glories in His
    subordinates in the kingdom because they were true to Him in trial. His associates in that
    glorious reign are honored in the measure in which they honored Him in His rejection.
    The same holds true of us. We, too, shall reign. Not, indeed, upon the earth, but in
    His celestial kingdom. "Faithful is the saying...if we are enduring, we shall be
    reigning together also" (2 Tim.2:12). Paul writes this to Timothy to show that the
    awards in that day will depend on our present conduct. From this standpoint it is easy to
    see how Paul can connect the walk of the Philippians with the day of Christ. It will be to
    Paul's glory to find many of them honored in that day, for it will reflect glory upon
    himself.
    A study of the contexts in which the day of Christ is designated by the addition of His
    name (Jesus Christ, Phil.1: 6), or another title (Lord Jesus Christ, 1
    Cor.1:8), or even when "Christ" is omitted (Lord Jesus, 1 Cor.5:5; 2
    Cor.1:14), will show that they all refer to the same time under slightly different
    aspects. In each case the added name or title accords with the theme.
    "He Who undertakes a good work in you will be performing it until the day of Jesus
    Christ." Here the expression "day of Christ" is enriched by the name which
    suggests His humiliation, the time of His suffering, which precedes and prepares for His
    glorification. To them also is this grace granted, to suffer for His sake (Phil.1:29). God
    started a work in them which would lead them along a path of pain, but He would not stop
    until it is complete, when the suffering is past and the glory begins--the day of the
    erstwhile suffering Saviour, yet now exalted Messiah. In that day their glory also will be
    greatly enhanced by the previous persecutions which they had endured. All this is
    suggested by the "day of Jesus Christ."
    "Who will be confirming you also to the consummation, unimpeachable in the day of
    our Lord Jesus Christ. God is faithful..." (1 Cor.1:8). In the opening of the
    Corinthian epistle we have a parallel to that in Philippians, but on a somewhat broader
    basis. Paul had many charges to bring against the Corinthians, but before he exposes their
    faults he reveals the great truth that a day was coming when they will be perfected in His
    presence, unimpeachable. They have failed to obey Him as Lord. They have denied a part of
    His salvation, they have misused His anointing, yet, in that day all this will be
    rectified. This is what the full title suggests. It is the day of Christ, when His
    salvation and His lordship will be fully acknowledged by the failing Corinthians. What a
    gracious assurance to give them before exposing their lack in this day!
    Conduct is connected with the title "Lord," and salvation with the name
    "Jesus." Hence, when dealing with a specially flagrant sin and the salvation of
    its perpetrator, he is given over to Satan for the extermination of the flesh "that
    the spirit may be saved in the day of the Lord Jesus" (1 Cor.5:5).
    Again, when Paul speaks of his conduct (2 Cor.1:12), and that of the Corinthians,
    he looks forward to the day of the Lord Jesus, when their good conduct will find
    its reward, and both will glory in each other on this account.
    It will thus be seen that the impending "day," which coincides with the next
    eon, is designated according to the special glory which each context requires, for then He
    will be in fact what He is now in faith. That day will be His day. It is the same
    time, whether it be the day of Jehovah or the day of Christ, or Jesus Christ or the Lord
    Jesus. It is the day of our Lord Jesus Christ, in which our salvation and service will
    come to its consummation, for we will be glorified by His grace and rewarded for our
    service and suffering in the present--man's miserable day.
