Indeed, Love is the most important of all. Paul was very persistent in saying that we could do wonders and miracles, we can make sacrifices and even give our lives for a cause or a person, but if there is no love involved, it is good for nothing. Yet, love is one of the most difficult things to show and give. why? Because we always do it in exchange of something, we all expect something back. The only One who can really love is God, because His love is totally unconditional. It's the AGAPE love, the kind of love that flows naturally from God but which takes an effort and an act of our will to show, practice and profess.
