Recite One Our Father, One Hail Mary and One Glory Be per day followed by the Novena Prayer:
O Lord our God,
You alone are the Most Holy King
And Ruler of all nations.
We pray to You, Lord,
In the great expectation of receiving from You,
O Divine King,
Mercy, peace, justice and all good things.
Protect, O Lord our King,
Our families and the land of our birth.
Guard us we pray Most Faithful One.
Protect us from our enemies
And from Your Just Judgment
Forgive us, O Sovereign King,
Our sins against you.
Jesus, You are a King of Mercy.
We have deserved Your Just Judgment.
Have mercy on us, Lord, and forgive us.
We trust in Your Great Mercy.
O most awe-inspiring King,
We bow before You and pray;
May Your Reign, Your Kingdom,
Be recognized on earth. Amen.
