This is the classic Catholic prayer to the Holy Spirit, asking for guidance, strength and an increased love of God.
Come, Holy Spirit, fill the hearts of Thy faithful and enkindle in them the fire of Thy love. Send forth Your Spirit and they shall be created. And You shall renew the face of the earth. O God, Who instructed the hearts of the faithful by the light of the Holy Spirit, grant by the same Spirit that we may be truly wise, and ever to rejoice in His consolation. Through Christ our Lord. Amen.
