The word which God sent unto the children of Israel, preaching peace by Jesus Christ: (he is Lord of all:)
The Greek is rough, I grant, but I take this as the preface to God's worthy work among the children of Israel: proclaiming peace by Christ. Peter recalls what was promised to the fathers under the eternal covenant, that all men knew, a Redeemer to restore what was decayed. He grounds his speech in what they already know, so they will credit what he now declares.
AI summary
Peter opened his mouth with freedom and weight, as a man who had been locked silent to the uncircumcised until God opened it. He first establishes what must be clear or neither he nor they could preach or hear with comfort: God respects no man's person, but judges by merit alone, and so the Gospel belongs to Gentile and Jew equally.

Commenting on Acts 10:34-43
Peter now enters his sermon itself: the doctrine he preaches is the Gospel, which God sent first to the Jews by the apostles' ministry. It comes from Him and is therefore of divine origin, not man's word but God's. That Christ sent the apostles to preach it proves His deity; He is Lord, and this word is His authority.
