You have heard the old saying that oil, and water, don't mix; and its true. But here is a new one for you; love, and words don't mix. Anyone can say "I love you"; but, does that make it so? Not necessarily. We all probably have had past lovers, that spoke these words, but didn't really mean them. If love can't reliably be shown by words, how can you tell if someone loves you? Simple, by their actions. Love can only truly be shown through demonstration.
What ever the relationship, love is always shown by one's actions. What good would it do for an infant to have it's mother, tell it how much she loves it, without the mother feeding, cuddling, nurturing, and paying attention to it? This is true with any relationship, parent-child, husband-wife, siblings, and our relationship with God.
They say a picture is worth a thousand words, well, a sincere gesture, or sacrifice, is worth a thousand love poems.
Love, is always a giver, never a taker. Love, does not take offense, and love is patient. Love does not change, even if people do. To love is to care, and to not care if it is reciprocated. True love, is not decided on the whims and desires, for it is eternal.
Everybody wants real love, but how many are ready to give it?
