All scripture points to the life, death and resurrection of Christ as the fulfillment of all the promises in the OT, The gospels shows this and teach it, Peter teaches it, John teaches it and Paul teaches it.. all one gospel message that salvation can be in no other than Christ.. The OT saints looked forward to the promise, the NT Christ fulfils it.
Also this is why Paul says we are all one in Christ there is only one ekklesia of God, one church (whatever you want to call god's people). Paul does this succinctly and in a straightforward manner:
Ephesians 2
11 remember that you were at that time separated from Christ, alienated from the
commonwealth of Israel and strangers to the covenants of promise, having no hope and without God in the world.....
13a But now in Christ Jesus you who once were far......
18-19 For through him we both have access in one Spirit to the Father. So then you are no longer strangers and aliens, but
you are fellow citizens with the saints and members of the household of God
21-22 in whom the whole structure, being joined together, grows into a holy temple in the Lord. In him you also are being built together into a dwelling place for God by the Spirit.
As Paul says both Jews and gentiles are built together as a holy temple in the Lord.
