In this sermon, the speaker emphasizes the importance of the 40 days that Jesus spent on earth after His resurrection. He explains that during this time, Jesus trained His disciples to shift their focus from external things to internal revelation, from the flesh to the Holy Spirit, and from the law to life. The speaker shares a personal anecdote about a turbulent airplane ride to illustrate the need for Christians to rise above fear and rely on the Holy Spirit. He concludes by urging the audience to prioritize their personal encounter with the Lord and the experience of being filled with the Holy Spirit.

The preacher, Greek Word Studies, delves into the concept of grumbling, which is an audible expression of unwarranted dissatisfaction or discontent, often done in low tones or behind-the-scenes. Grumbling can reflect secret debates or displeasure not openly avowed, as seen in the Bible verses where it is mentioned. The sermon emphasizes the importance of avoiding grumbling, as it can lead to a lack of trust in God's sovereignty and provision, contrasting unbelief with grumbling in Scripture.

Favell Lee Mortimer reflects on how sinners, including Jesus' own relatives, scorned and disbelieved Him, urging believers to be patient in facing similar trials. The world, the rich, and the learned hated Jesus for exposing their evil deeds, showing that faithful Christians will face persecution for standing up for righteousness. Despite being goodness itself, Jesus was only faintly praised as 'a good man' by some, while others falsely accused Him, highlighting the worthlessness of worldly esteem. Mortimer emphasizes the contrast between the perfect qualities of Jesus and the base nature of humanity, encouraging Christians to trust in God's timing and providence, just as Jesus did.
