That's what's on my mind these days. There's a lot of schools of thought on it... but I think what's universal, is that LOVE is answer to almost any question you ask.
Martin Luther King, Jr's teaching on love:
"Eros..a romantic love for your mate. It's inevitably a little selfish. You love your lover because there is something about your lover that moves you. It may be the way he talks or the way he walks or the personality or the physical beauty or the intellectual power-- but it's always based on that there's something that attracts you.
Philia...intimate affection between personal friends. These are people you like. It's reciprocal love. You love because you are loved. You love the people that you like. People that you like to sit down at the table and eat dinner with. People you dial the phone and talk to. People you go out with. This is friendship.
Agape...is more than romantic love... more than friendship...it's understanding. It is creative and redeeming good will toward all men. It is the love of God operating in the human heart. It is the overflowing love which seeks nothing in return. And when you rise to love on this level, you love people who don't move you. You love those that you don't like. You love those whose ways are distasteful to you. You love every man because God loves him."
Love is always the giver, never the taker. Real love doesn't ask for anything in return. Where there is love, there is no fear.
"We can do no great things, only small things with great love."
