What does the Bible say about Ananias and Sapphira?

In Acts 5:1-11, Ananias and Sapphira sold a possession but kept back part of the money while pretending to donate the full amount. Peter confronted them, revealing that they were lying not just to the apostles but to God himself. This act exposed their hearts, showing they did not possess a genuine relationship with Christ and ultimately led to their death as a judgment from God. This narrative emphasizes the seriousness of dishonest intentions within the Christian community and illustrates the importance of having a heart genuinely aligned with the grace of God.
