The Holy Spirit is the Sovereign Executive of witnessing
And he (Holy Spirit), when he comes, will convince the
world concerning sin, and righteousness, and judgment.
Concerning sin, because they do not believe in me
(expanded tran., John 16:8,9).
Jesus prophesied the coming of the Holy Spirit on the day of
Pentecost (Acts 2:1-4).
In dealing with the unbeliever, the Holy Spirit emphasizes
one sin only--- the unpardonable sin ----
rejection of the Lord Jesus Christ!
But as for me, I will always have HOPE, I will praise God more and more.
