John Gill preaches on 'The Law in the Hand of Christ,' emphasizing that the ark of the covenant symbolizes Christ, who embodies the law and fulfills its demands. He explains how the two tables of stone represent the moral law, which remains unchanged and is fulfilled in Christ, who is both the lawgiver and the one who bears the penalty for sin. Gill highlights that while the law is no longer a covenant of works for believers, it continues to guide them in their conduct under grace. The sermon concludes with the assurance that through Christ, the law is not a source of condemnation but a means of grace and guidance for believers.
