"Perfect love casts out fear." It is not be thinking ourselve sright that we cease to fear. It is simply by loving, and abandoning ourselves to the One whom we love without returning to self. That is what makes death sweet and precious. When we are dead to ourselves, the death of the body is only the consummation of the work of grace.
God, unto whom all hearts are open, unto whom all will
is spoken, unto whom nothing is hidden,
I beseech Thee to cleanse the intent of my heart
with the unspeakable gift of Thy grace that
I may perfectly love Thee and worthily praise Thee.
