Prayer (from Roman Catholic tradition):

Come Holy Spirit, fill the hearts of your faithful and kindle in them the fire of your love. Send forth your Spirit and they shall be created. And You shall renew the face of the earth.

O, God, who by the light of the Holy Spirit, did instruct the hearts of the faithful, grant that by the same Holy Spirit we may be truly wise and ever enjoy His consolations.

Affirmation:

The Holy Spirit flares its cleansing, purifying flames throughout my soul and body, and I am made whole and perfect. 
(from Keeping a True Lent)

Scripture:

All of them were filled with the Holy Spirit and began to speak in other languages, as the Spirit gave them the ability.
(Acts of the Apostles 2:4)
