Romans 10:6

ἡ δὲ ἐκ π. δ. A personification, a dramatisation of the appeal of the Gospel to man, to make plain the nature of the demand made by it, in contrast to the demand made by the Law. The demand of the Gospel is not for impossible effort, but for trust and confession. Note that S. Paul finds faith-righteousness already included in O. T. teaching; cf. Romans 4:13 f.; Giff. on Romans 10:10.

μὴ εἴπῃς κ.τ.λ. The allusions are to Deuteronomy 30:11 f. The questions, which are set aside, embody the hesitations of the man who supposes that the facts, on which this righteousness is based, are dependent upon human activity, whereas they are the accomplished acts of GOD in Christ; and what is demanded is trust in Him who has done these acts, and confession of His Lordship.

τοῦτ' ἔστιν. Simply explanatory = that is to say; so in Romans 10:7-8.

Χριστὸν καταγαγεῖν … ἐκ νεκρῶν�. The reference is to the Incarnation and Resurrection. These are the fundamental acts of GOD by which His righteousness is revealed, and made possible for man. The fact that they are GOD’S acts determines the human condition of righteousness, namely, faith in GOD through the incarnate and risen Son, and consequent confession of Him; cf. Philippians 2:1-11.
