Paul is the first author of the NT who stresses the central biblical-theological theme of ‘promise and fulfilment’. He is doing so as apostle of the righteousness of God: the One God remains true to Himself as the ‘God of hope’ (Rom 15.13); sending His son to save the world of sinners He says his ‘Yes’ to all He has given in His grace to His people (2 Cor. 1.20), and He creates the eschatological act of redemption which is radically new in opening the Kingdom of God (Rom 14.17). In the horizon of his theology of justification, Paul discovers what God has promised to Abraham; in the horizon of his theology of promise, he discovers what God fulfils in justifying Jews and Gentiles by their faith. Paul's theology, maturing from Galatians to Romans, gives a good measure for Christian talk of promise and fulfilment in dialogue with the Jews.
