Communion experience. The greatest love we can feel in this life is God's love for us, for it is the greatest possible love. After I received the Lord in the Eucharist, the Holy Spirit filled my heart with overflowing joy. I felt as if a might force from within my heart was trying to bust open its walls. The joy was powerful, vigorous, and absolutely soul-touching – I couldn't do a thing about it. I knew that it came from the love of Christ.
