ANSWER: Acts 15:9 is an undoubted proof text of this experience in the case of the Apostles and other disciples. The fulness of the Spirit is sometimes emotional rather than sanctifying. This is often the case when the Spirit descends upon a multitude, filling them with joy, entirely sanctifying those who are aspiring after this grace and regenerating penitent seekers of pardon and convicting sinners. The spirit of adoption crying in the heart, "Abba, Father," fills the convert with a feeling of fullness. For these reasons, Wesley did not employ this phrase, "Fullness of the Spirit," to denote entire sanctification, although he used at least a score of synonymous terms to denote this experience.
