This is the time during which the very first novena of the Church Age was made, when Mary and the Apostles prayed from Christ's Ascension to the Pentecost, a period of nine days (Acts 1-2).
Fourth Day:
Come, O Blessed Spirit of Fortitude, uphold my soul in times of trouble and adversity, sustain my efforts after holiness, strengthen my weakness, give me courage against all the assaults of my enemies, that I may never be overcome and separated from Thee, my God and greatest Good. Amen.
Recite one Our Father, one Hail Mary, and seven Glory Be's
