A.B. Simpson emphasizes the sensitivity of the Holy Spirit, comparing it to the delicate nature of love that cannot be won through force but through trust and affection. He illustrates that just as one cannot conquer a woman's heart with harshness, the Holy Spirit requires a gentle and unwavering faith to operate freely in our lives. Simpson urges believers to 'Speak to the Rock' rather than strike it, highlighting the importance of treating the Holy Spirit with tender confidence. He encourages the congregation to fully open themselves to the Spirit's fullness, receiving His life with the trust of a child or a bride. The sermon calls for a deep, faith-filled relationship with the Holy Spirit, akin to the nurturing bond between a flower and sunshine.
