The sermon contrasts the inferiority of Old Covenant animal sacrifices with the perfect and sufficient sacrifice of Jesus Christ. It emphasizes that while old rituals only reminded believers of their sins, Christ's offering permanently removes sin and purges the conscience. By fulfilling the will of God through his incarnate body, Jesus established a new covenant that sanctifies believers forever. The text highlights that this single, once-for-all act is wholly adequate for salvation, requiring no additional religious works or repeated offerings. Consequently, Christians are called to rest in the assurance of complete forgiveness and acceptance through faith alone.

The sermon examines Joshua chapter 3, focusing on the miraculous division of the Jordan River as a testament to God's power and faithfulness. It highlights the Ark of the Covenant as a symbol of God's presence, urging believers to fix their eyes on Jesus Christ. Mr Mitchell emphasizes that true faith requires active obedience, even when facing seemingly impossible obstacles or overwhelming circumstances. Drawing parallels between Joshua and Jesus, the message encourages the congregation to trust in the living God who controls all creation and intervenes for His people. Ultimately, the text calls for a life of bold confidence and contentment rooted in knowing God's sovereignty and provision.
