If Christ Jesus is the `first` then there must be others to follow.   We are to be Sons Of God - not sinners saved by Grace.   

We can only manifest as Sons Of God when we are Spirit Filled with transformed minds.   

Christ died:
   → to keep us from having to go to Hell
   → to enable us to be Born Again as New Spirit beings
   → to baptize us with His Holy Spirit
   → to enable us to partner with Him in the Kingdom work
   → to enable us to manifest the character and power of His Holy Spirit
   → to empower us to rule and reign in the Earth
   → to keep us in eternal intimate personal relationship with Him

And not only they, but ourselves also, which have the firstfruits of the Holy Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body. Rom 8:23

For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches. Rom 11:16

But now is Christ risen from the dead, and become the firstfruits of them that slept. 1Co 15:20

But every man in his own order: Christ the firstfruits; afterward they that are Christ`s at his coming. 1Co 15:23

Of his own will begat he us with the word of truth, that we should be a kind of firstfruits of his creatures. Jam 1:18

These are they which were not defiled with women; for they are virgins.     These are they which follow the Lamb whithersoever he goeth.     These were redeemed from among men, being the firstfruits unto the Lord and to the Lamb. Rev 14:4
