T. Austin-Sparks emphasizes the significance of following the Lamb, Jesus Christ, who was foreordained as the sacrificial Lamb from the foundation of the world. He explains that this following is not merely about salvation but involves a deep commitment to God's eternal purpose, which requires a profound transformation through the Cross. The sermon highlights the paradox of the Lamb's meekness and strength, illustrating how true power is found in submission and yieldedness to God's will. Ultimately, Sparks calls for believers to embrace the Cross as the means to fulfill God's purpose and achieve unity among His people, as exemplified by the one hundred and forty-four thousand who follow the Lamb in unison.
