On Lutheran Via de Cristo retreat weekends, we pray this prayer for enlightenment before each talk given.
Come Holy Spirit, fill the hearts of your faithful and kindle in us the fire of your love. Send forth your Spirit, and we shall be created. And you shall renew the face of the earth.
O God, who by the light of the Holy Spirit instructs the hearts of the faithful, grant, that by the same Holy Spirit we may be truly wise and ever rejoice in his consolations. Through Christ our Lord. Amen.
