In the above quotation from J.I. Packer’s book, Evangelism and the Sovereignty of God. we can see the work of the Holy Spirit in at least there ways.
1. The Holy Spirit Empowers the evangelist. While it is true that the message of the Gospel can be presented as if it’s a matter of mere facts, or an intellectual exercise, the sharing of the Gospel message In the power of the Holy Spirit carries with it certain Divine authority that is not lost on the hearer.
2. The Holy Spirit opens the heart of the hearer to receive the Gospel message. While it is also true that the Gospel message can be heard by anyone at all, a God-opened heart guarantees that it will be taken to heart, received with gladness, and a lost soul saved for eternity. No better example can be found than the woman Lydia in the 16th Chapter of the book of Acts.
3. The Holy Spirit no only empowers the evangelist and opens the heart of the sinner, He also empowers the new born believer to live for God and serve Him from that day forward.. It is the Holy Spirit that works in the Christian both to desire and to do what is pleasing to his Lord. (Phil 2:13).
