St. Josemaria Escriva’s mission in the Church was to emphasize the importance of the present moment and current circumstances — this is what we have to offer to God. Nothing else.
This prayer of his to the Holy Spirit is perfect for those of us who need help remembering that the time to choose love is now:
Come, O Holy Spirit! Enlighten my mind to know your commands; strengthen my heart against the snares of the enemy; inflame my will… I have heard your voice, and I don’t want to harden myself and resist, saying “Later…, tomorrow.” Nunc coepi! Now I begin! In case there is no tomorrow for me. O Spirit of truth and wisdom, Spirit of understanding and counsel, Spirit of joy and peace! I want whatever you want. I want because you want, I want however you want, I want whenever you want.
