Acts 10:44–48 (ESV)
The Holy Spirit Falls on the Gentiles
44 While Peter was still saying these things, the Holy Spirit fell on all who heard the word. 45 And the believers from among the circumcised who had come with Peter were amazed, because the gift of the Holy Spirit was poured out even on the Gentiles.
46 For they were hearing them speaking in tongues and extolling God. Then Peter declared, 47 “Can anyone withhold water for baptizing these people, who have received the Holy Spirit just as we have?” 48 And he commanded them to be baptized in the
name of Jesus Christ. Then they asked him to remain for some days.
Notice that Peter preaches/teaches the Word and the Holy Spirit does the rest. The covert, convicting, and changing is all the work
of the Holy Spirit. Luther states: “[Faith is] a living spiritual flame, by which hearts are set afire, born anew and converted through the Holy Spirit, so that they desire, will, do, and are exactly what the law of Moses expressly commands and
requires [Jer 31:33; 2Co 3:3; Rm 3:27; 8:2; 2Co 4:13].… For the living Word of Christ, when preached, imparts the Spirit, who writes the law of God in our hearts with living fire, as happened to Cornelius in Acts 10 [:44], and again Gal. 4 [3:2]: ‘Did
you receive the Spirit by works or by the preaching of faith?’ Hence the gospel is called a word of life in John 6[:68]” (AE 36:200–201).
I pray: O Lord, I received the gift of the
Holy Spirit when I was baptized. Let the Holy Spirit continue to work in me, molding me into your image, and living your will. I look forward to the day you take me to heaven and that work will be complete. Until then, guide me O Holy Spirit.
