Yes it does. Non-Christian Jews. Non-Christian gentiles and Christian Jews and Gentiles.
The body of Christ is the co-heirs Israel and church.
The church is all believers from the resurrection of Christ to the rapture.
But that is irrelevant to dispensations.
Here is my view dispensation.
Innocence
Conscience
Mosaic law for Israel while conscience for everyone else. Israel was supposed to be the nation of missionaries. It failed.
The church age. But for the beginning conscience still was active in the world. The church is failing as well.
At the rapture the new covenant to the houses of Israel and Judah. Israel will then succeed at being missionaries. But mankind will continue in rebellion.
Then eternity.
Here is more classical view.

Covenant theology does away with Israel, but the Bible does not.
After the rapture the groups are Israel, tribulation saints and everyone else.
In the MK it is Israel, Gentile Saints and everyone else.
What never changes is the grace of God and the blood of Christ, whether by promise or immediate fulfillment via the Holy Spirit.
