What does it mean that the Holy Spirit has power over the hearts of men?

The assertion that the Holy Spirit has power over the hearts of men highlights His unique ability to change and influence human will and desire. While human effort can lead to outward conformity, only the Holy Spirit can penetrate the heart to bring true transformation. As mentioned in the sermon, the Scriptures affirm that it is only through the Holy Spirit that the hardened heart can be softened (Ezekiel 36:26). This divine power is necessary to effectuate genuine repentance and faith, which are crucial for salvation. The Holy Spirit works to overcome resistance and make individuals receptive to the Gospel, demonstrating that the true change of heart is a work of God rather than of human endeavor.
