Another quote here from St. Bonaventure. He actually is speaking of the Sacred Heart of Jesus, the feast we celebrated several days ago.
“Not only ‘see in his hands the print of the nails,’ with the apostle Thomas, not only put your finger into the place of the nails, not only put your hand into his side, but enter with your whole being through the door of his side into Jesus’ heart itself.” — St. Bonaventure, OFM
The invitation is there. The grace is available. For us to enter that deeply into the heart of Jesus, our hearts need to be open to that grace and invitation.
