Hans R. Waldvogel emphasizes the transformative power of the Holy Spirit in the life of a believer, urging that true sanctification comes not from self-effort but from allowing Christ to dwell within us. He highlights Jesus' call to be glorified in us, which is a divine invitation to reflect His holiness and character. Waldvogel stresses the importance of obedience to God's word and the necessity of conviction in our spiritual journey, as it indicates the presence of the Holy Spirit. He illustrates that just as a lamp requires electricity to shine, we must be filled with Christ to fulfill our purpose as His workmanship. Ultimately, the sermon calls for a deep, personal relationship with Jesus that leads to continual transformation into His likeness.
