Fulton J. Sheen said this quote
“ All love on this earth involves choice. When, for example, a young man expresses his love to a young woman and asks her to become his wife, he is not just making an affirmation of love; he is also negating his love for anyone else. In that one act by which he chooses her, he rejects all that is not her. There is no other real way in which to prove we love a thing than by choosing it in preference to something else. Word and signs of love may be, and often are, expressions of egotism or passion; but deeds are proofs of love. We can prove we love our Lord only by choosing Him in preference to anything else. ”
