While our limited knowledge and understanding of things will come to an end, love will persist forever. All who obey His Commandments abide in Him, and He abides in them. No Christian actions can be performed without active love. If you are kind to someone, it is because you love the person in Christ. If you are feeding the hungry or clothing the sick, such charitable acts are acts of love.
Love is perfected by our charitable acts towards others.
What we do to others, we do to Christ. In today's Gospel Reading, our spiritual minds perceive how God manifested His Divine love in a very personal way. Through the incarnation in Jesus Christ, God came to dwell among us. There are no other like Him. When God came down from Heaven to dwell upon us, not all accepted the manifestation of His Divine love.
