The saying “facts don’t care about your feelings” is often used to give a listener unwelcome news … but in this case, it brings very good news indeed! You have received our Lord’s body and the abundant grace that comes with it, no matter what your emotions are telling you.
You don’t give our Lord the love He deserves? Join the club! I don’t either. In fact, I’d submit that no one has ever managed to show Him the love He deserves, or ever could. Accept the gift of His body and blood. Accept that–just like the rest of us–you’ll never be able to repay it adequately. And trust in the grace that His body & blood have given you. It’s stronger than the “limits” that we all have and share.
