Peter faces a crucial moment: should these Gentiles be baptized? His question reveals a profound truth about God's actions and our response.
Peter's rhetorical question, 'Can anyone withhold water for baptizing these people, who have received the Holy Spirit just as we have?', isn't just a suggestion; it's a declaration.
God's Initiative
Notice Peter's emphasis: 'who have received the Holy Spirit just as we have.' God acted first! He poured out His Spirit on Cornelius and his household before Peter even finished speaking. This wasn't a reward for something they did; it was a sovereign act of God's grace, demonstrating that salvation is for everyone, Jew and Gentile alike.
The Sign Follows the Substance
Because God had already given the 'inward and spiritual grace' – His Spirit – Peter argues that the outward sign, water baptism, must follow. It's like receiving the deed to a house; you then claim the physical structure. The Holy Spirit's presence is the undeniable evidence that these individuals are fully accepted by God and belong to Christ's body. To deny them baptism would be to deny the very work God had just visibly accomplished. It completes the picture: God gives the Spirit, and we respond with the commanded sign.
