Faith in Jesus is the absolutely crucial response to God's grace and is such a life-transforming blessing. For the jailer, faith meant hearing the gospel of Jesus as Lord and responding by believing that message, being baptized immediately, demonstrating a life change, and sharing in fellowship with other believers (cf. Acts 2:42-47). Imagine going from being the jailer over men to washing their wounds in your own home! Think about being responsible for the painful incarceration of men, then have these men baptize you and your family that same night! Imagine locking in chains men who would later sit at your table sharing a meal! Isn't God incredible! Isn't his grace indescribable! No wonder we rejoice when those who are lost truly believe! Life is forever different.
