How do we know salvation is for everyone who believes?

In Acts 10, the experience of Cornelius and his household demonstrates that salvation through Jesus Christ is accessible to all who believe. Peter asserts the universal nature of the gospel, highlighting that anyone who believes in Christ will receive the remission of their sins (Acts 10:43). This truth is echoed throughout Scripture, assuring us that whosoever believes in Him shall be saved, reinforcing the doctrine that salvation extends beyond ethnic boundaries. The outpouring of the Holy Spirit upon Gentiles signifies that faith in Christ is the sole requirement for salvation, unifying all believers as members of the body of Christ.
