How do we know Cornelius was saved?

Cornelius serves as a pivotal figure illustrating God's grace toward Gentiles. The text describes him as a devout man who feared God with all his household, gave alms generously, and prayed continuously (Acts 10:2). These characteristics reflect the evidence of true saving faith. Moreover, God recognized his sincerity, as seen when the angel informs him that his prayers and alms had come up as a memorial before God (Acts 10:4). This shows that he was seeking the true God and positioned him to receive the gospel message that Peter would deliver, affirming his state as a chosen child of God who had received saving grace.
