At the heart of this sermon lies Matthew 16:18, a powerful declaration by Jesus Himself. In this verse, Jesus asserts the invincibility of His Church against the onslaught of evil, symbolized by the gates of hell. It vividly illustrates Christ's victory over death and His establishment of a community that embodies His redemptive love and grace. This verse serves as a rallying cry for believers, inspiring them to stand firm in their faith and to actively participate in the ongoing work of the Church, spreading the message of salvation and hope to a world in need.
