I don't know how true it is, but I have heard that swans mate for life. If they don't, I wish they would. There is nothing more beautiful than loving commitment over one's lifetime. Symbols like the heart always represent love and that is a good thing. However, there is more to love than just a warm fuzzy feeling or infatuation. Real love means commitment and caring. Caring enough to do the best thing for your mate (or your children) regardless whether it is wanted or even appreciated. Proverbs puts it this way...
Proverbs 3:11-12 (WEB)
11) My son, don’t despise Yahweh’s discipline, neither be weary of his reproof:
12) for whom Yahweh loves, he reproves; even as a father reproves the son in whom he delights.
You do what you have to do if you really love someone. It may not be pleasant at times, but regardless, it must be done. God loves me because he has told me so and because he gives me instruction (reproof: a bringing to light of something) through his word. I may not enjoy realizing I have sinned in one way or another, but if it draws me closer to God then it is worth it. Funny thing, it brings my heart closer to his and that brings us back to the swan heart picture above. Not a bad thought on a cloudy day like this one....
