William MacDonald emphasizes the triumph and victory found in Christ, drawing parallels between a military victory parade and the Christian journey. He explains that while believers carry the sweet aroma of Christ, it is perceived differently by others; to the faithful, it signifies life, while to the unrepentant, it represents death. MacDonald highlights that God is glorified in both the salvation of the repentant and the judgment of the lost, underscoring the solemnity of these outcomes. He challenges the notion of measuring success solely by conversions, suggesting that rejection of the Gospel also serves to glorify God. The sermon concludes with a poignant reminder of the weight of this responsibility, echoing the Apostle's question, 'Who is sufficient for these things?'
