Featured Mixing the Metaphors

The entire history of the world is established on this principle. The death and resurrection of Jesus Christ was on the fifth day. It is also the introduction of the grace of God whereby the gospel of God, the theme of the NT, begins to be preached to the nations. The number 5 is the number of God for grace.and the first line of text that shows up in the scriptures that is addressed to the nations goes like this;

Rom 1:1 Paul, a servant of Jesus Christ, called to be an apostle, separated unto the gospel of God,

The definition of the gospel of God is given here:

Rom 16:24 The grace of our Lord Jesus Christ be with you all. Amen.
25 Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,
26 But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:
27 To God only wise, be glory through Jesus Christ for ever. Amen.

If you want to know what Paul means that he is separated unto the gospel of God, see here;

Ga 2:2 And I went up by revelation, and communicated unto them that gospel which I preach among the Gentiles (the gospel of God), but privately to them which were of reputation, lest by any means I should run, or had run, in vain.
3 But neither Titus, who was with me, being a Greek, was compelled to be circumcised:
4 And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage:
5 To whom we gave place by subjection, no, not for an hour; that the truth of the gospel might continue with you.
6 But of these who seemed to be somewhat, (whatsoever they were, it maketh no matter to me: God accepteth no man's person) for they who seemed to be somewhat in conference added nothing to me:
7 But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;
8 (For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles)
9 And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.

Separation means, not a difference in the gospel of Jesus Christ, but a difference in the intended audience. The Jewish apostles continued to evangelize those of the stock of Jacob in the region of Judah and Asia Minor. Read the letters of Peter, James, John, and Jude. They wrote to the strangers, the twelve tribes scattered abroad. None of these apostles went to Europe where the gentiles live. Only Paul went there to tell them that now, since Jesus Christ has made an atonement for their sins , and God the Father has accepted it on our behalf, all can be saved. So, the gospel of God, the gospel of grace, was dependent upon the gospel of Christ. And that is what we are told in Romans 1.

The gospel of God concerns the gospel of Jesus Christ; Read it.

Rom 1:3 Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh;
4 And declared to be the Son of God with power, according to the spirit of holiness, by the resurrection from the dead:
5 By whom we have received grace and apostleship, for obedience to the faith among all nations, for his name:
6 Among whom are ye also the called of Jesus Christ:

In other words, there would be no salvation for the gentiles if there had not been the death and resurrection of Jesus Christ in our place.

Paul is specifically called and equipped to be our apostle and to tell us in his letters what God expects from us.

Romans 15:15 Nevertheless, brethren, I have written the more boldly unto you in some sort, as putting you in mind, because of the grace that is given to me of God,
16 That I should be the minister of Jesus Christ to the Gentiles, ministering the gospel of God, that the offering up of the Gentiles might be acceptable, being sanctified by the Holy Ghost.
17 I have therefore whereof I may glory through Jesus Christ in those things which pertain to God.
18 For I will not dare to speak of any of those things which Christ hath not wrought by me, to make the Gentiles obedient, by word and deed,

So God for 4000 years, or four of his days, has prepared the world for his salvation, and is busy presenting his salvation systematically in his last three days. At the end of the three days, all that are left alive on the earth will be saved and glorified and those who would not be saved will be destroyed. God cannot fail in his purpose and at the end of day 7 time shall be no more.
