In this sermon, the speaker emphasizes the importance of being fully committed to serving the Lord. He refers to the letter written by Paul to Timothy, where Paul instructs Timothy to be diligent in his work and to pay close attention to himself and his teaching. The speaker highlights that this instruction applies not only to preachers but to all believers who have the opportunity to teach others, whether it be through conversations with friends, family, or counseling. The sermon also emphasizes the need for personal growth and progress in one's spiritual life, moving beyond a superficial understanding of Christ's birth and miracles to a deep and genuine relationship with Him.

In this sermon, the speaker shares two stories of missionaries and their experiences with preaching the word of God. The first story is about a missionary who was asked to give a speech in Japanese at a party. Despite not knowing the language, he spoke for 25 minutes in fluent oratorical Japanese, guided by the Holy Spirit. The second story is about Duncan Campbell, a preacher who experienced a powerful revival after a young man led a heartfelt prayer. The speaker emphasizes that it is not the length or eloquence of a sermon that brings about change, but rather the work of God. The sermon also touches on the importance of trusting in God's power and handling persecution with faith.

John Chrysostom preaches about the importance of recognizing Jesus as a man sent from God, proven through miracles and signs, and how the crucifixion of Jesus was part of God's plan despite the wicked actions of men. He emphasizes the significance of Christ's resurrection, highlighting that it was not possible for death to hold Him, and how David's prophecy foretold of this event. Chrysostom urges the audience to embrace meekness and gentleness over anger and wrath, illustrating the detrimental effects of giving in to rage and the importance of following Christ's teachings to avoid falling into the devil's destructive ways.

T. Austin-Sparks emphasizes the exaltation of the Lord Jesus as central to understanding spiritual fullness and power in the life of believers. He connects the Lordship of Christ with the necessity of spiritual conquest, illustrating that true fulfillment comes only when individuals and the Church recognize and submit to Christ's sovereignty. Through biblical examples, Sparks demonstrates that spiritual power is contingent upon acknowledging Jesus as Lord, and that any attempt to attain spiritual fullness without this recognition leads to limitation and conflict. He concludes that the Holy Spirit's role is to establish this Lordship in believers, enabling them to serve effectively and experience the fullness of Christ.
