We are under the new covenant now. The only difference between the Old Covenant and the New Covenant is that the testator died so that the beneficiaries could inherit. What do they inherit? The Kingdom. Eternal life. The mystery. The riches God has prepared for us in ages to come.
Think of it as a will.
The "mystery" in Paul's epistle to the Ephesians is a more complete understanding of the truth (originally revealed to Peter) that "the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel." [Ephesians 3:6]
In the Old Covenant, and in the promises given to Abraham, Isaac, and Jacob, possessing the land of Canaan
was the central and perhaps the most prominent item. But in the New Testament, possessing the land seems to have become a non-issue. The Jews occupied the land, and Jerusalem, but they were under Gentile dominion, and were part of the Roman Empire, in New Testament times. The Herodian rulers were nominally Jews, although of Edomite descent.
Hebrews 11:16 puts the literal land into the category of type
, by the statement, alluding to the patriarchs of old, "But now they desire a better country, that is, an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city." [Hebrews 11:16]
Here, the heavenly city, the New Jerusalem, is put in the place of the promised land. The author of Hebrews showed that as when the Israelites entered the promised land, this heavenly city is only entered by faith. "Now faith is the substance of things hoped for, the evidence of things not seen." [Hebrews 11:1]
The literal land, I think, represents the spiritual things promised to the saints. This includes the promise that the Spirit would guide the church into all truth
. The "mystery" was no doubt an example of this.
In the parables of Jesus, the kingdom of God is often associated with a wedding. Christ is presented as the bridegroom. In Revelation 19:7, John identifies the heavenly city as the bride and wide of the Lamb.
The New Covenant is not only a will, but a marriage covenant
. There is an analogy between the seven years that Jacob labored for his bride Rachel, daughter of Laban, and the seventieth week in Daniel 9:24-27. In the 70th week, Jesus "confirms the covenant with many." This 70th week includes the half week of the ministry of Jesus on earth, (three and a half years, if John's ministry is included) and a final symbolic half week, that spans the whole age of the church. In the first half week, Jesus qualified, by his righteous life and his death, to inherit all the promises of God, and in the second half-week he qualifies us
