and so that the Gentiles [also] may honor God for His mercy, as it is written [Psa. 18:49], "Therefore, I will praise you among the Gentiles and sing to your name."

[This happened] so that the blessing [promised] to Abraham might be received by the Gentiles through [the person and work of] Christ, so that we might receive the promised [gift of the] Holy Spirit through [our] faith [in Jesus].
