Acts 10:36

The word. That is, the message, the tidings of the Messiah, which brought peace on earth through a Saviour who is Christ the Lord. This was first preached to Israel as God’s chosen people, but now Peter recognized that God is the remitter of sins to everyone who believes on Him. The message of peace now was to be not only between God and the chosen race but also between God and the Gentiles.

Preaching. A form of the Greek verb euaggelizo, “to declare glad tidings,” and, in a technical Christian sense, “to preach the gospel.”

Peace. God is said to create peace for him that is afar off, as well as for him that is near, for the Gentile and for the Jew. Christ preached this peace between God and all nations without distinction. The apostles carried this good news to the world. Speaking to the Gentiles, Paul says, “Ye who sometimes were far off are made nigh by the blood of Christ.” The apostles preached always that there was no name under heaven by which men could be saved but the name of Christ, and that whether men be Jews or Greeks, Christ is all and in all. Hence, in this doctrine of peace through Christ there is harmony between OT and NT, between prophets and apostles. Christ is Lord of all.

The peace that is promised is a peace, not primarily between men, but between God and each man, and is obtained when atonement is received through Jesus Christ by faith. The messenger of peace is Jesus Christ; the basis of peace is His atoning work; the terms of peace are faith; the blessing of peace is the remission of sins; the fruit of peace is holiness.

Lord of all. Inasmuch as Jesus Christ is Lord of all, every man must stand on an equal footing before Him. By saying this, Peter also safeguarded Cornelius against thinking that the Jews whom he understood was the Messiah, was only a prophet and a teacher.
