While St. Gertrude was offering a certain action to God, saying:
O Lord, I offer Thee this work through Thine Only Son, in the power of the Holy Spirit, to the praise of Thine eternal Majesty; it was revealed to her that whatever action was thus offered would acquire a worth and acceptableness to God beyond all human comprehension. For as all things appear to be green when seen through a green glass, so whatever is offered to God through His Only-begotten Son cannot be otherwise than most precious and pleasing in His sight.
That you may understand how useful it is to offer all your works to God, listen to what our Lord said on one occasion to St. Gertrude: All thy works are most perfectly pleasing to Me. And as she could not believe this, He added: If you held in your hand some object which you had the means and the skill to render perfectly pleasing to everyone, and if you tenderly loved that object, would you neglect to adorn it? Even thus, because you are accustomed to offer all your works to Me, I hold them in My hand; and as I have both the power and the skill, My love rejoiceth to cleanse and perfect them all, that they may be most perfectly pleasing in My sight.
St. Gertrude the Great – Daily Prayers: During the Day
O MOST sweet Jesus; I commend to Thy Divine Heart all that I have done in the hour that is gone; to be cleansed and purified, and offered to God the Father for His eternal praise. And whatsoever I shall do in the hour that is beginning; I resolve to do simply and purely for the glory of God and for the salvation of all mankind; in union with Thy Passion. Amen.
Our Lord directed St. Gertrude to tell a certain person to form the following intention before beginning any work:
O LORD Jesus; in union with Thy most perfect actions I commend to Thee this my work; to be directed according to Thine adorable will; for the salvation of all mankind. Amen.
O LORD Jesus; in union with Thy most perfect actions I offer Thee this my work; to be amended and cleansed; and presented as is fit to God the Father; to His eternal praise. Amen.
Our Lord said to St. Gertrude: He who takes care to eat and drink; etc.; with the intention expressed in the following prayer; holds as it were a buckler before Me; to defend Me from the insults and injuries of the worldly.
O LORD Jesus, I take this food in that same love wherewith Thou hast sanctified it, when in Thy most holy Humanity Thou didst deign to eat and to drink to the glory of God the Father, and for the salvation of all the whole human race; beseeching Thee that, in union with Thy Divine love, it may tend to the increase of glory, and salvation of all Thine elect in Heaven, on earth, or in Purgatory.
WHILE TAKING SUSTENANCE
St. Gertrude was accustomed to say frequently while eating:
MAY the virtue of Thy Divine love incorporate me wholly into Thee, O my most loving Jesus!
And while drinking:
O MOST loving Jesus, pour into my heart and preserve within me the energy of Thine Own most glowing charity; may it pervade all my substance, and flow ever more through every faculty of my body and soul, to Thine eternal praise and glory. Amen.
She asked our Lord whether He would accept a like devotion from all who might offer it to Him, and received this reply: Whenever anyone eats or drinks with this intention and devotion, I will acknowledge in presence of My Father that I have eaten with Him, and that he has given Me to drink, and I will show to him in due time the utmost tenderness of My love.
AFTER FALLING INTO SIN
St. Gertrude said to our Lord: Teach me, O best of Teachers, how to efface the stains of sin which I contract from time to time. She received this answer: Never allow these stains to remain upon thy conscience; but as soon as thou feelest thyself defiled by any fault, say to Me with a devout heart:
O CHRIST Jesus, my only Salvation and Hope, grant that all my transgressions may be blotted out by Thine most efficacious death. Amen.
