The Lord Jesus speaks to his disciples regarding the work of the Holy Spirit as the remedy to the sorrow that has filled their hearts. The Holy Spirit will work in the world and in the church to glorify Jesus Christ. Bringing people to a true knowledge of Jesus is the primary work of the Holy Spirit. Since it is He who must do the work, all are entirely reliant upon Him for a saving knowledge and faith in Christ. The one who knows and experiences this truth is necessarily committed to prayer, relying upon the Spirit in all things.
Has the Holy Spirit worked in your heart?
