There are four types of love in the Bible
Agape: God's unconditional love for his children. The love we should have for God and for our brothers and sisters in Christ
Eros: Romantic love (the mushy, slushy love)
Philia: Love between friends and equals, the Love David has for Jonathan comes to mind here
Storge: Love between parents and children.
When I think of Love certain passages come to mind first and foremost how much God loves us.
Romans 5:6-8 [SUP]6 [/SUP]You see, at just the right time, when we were still powerless, Christ died for the ungodly. [SUP]7 [/SUP]Very rarely will anyone die for a righteous person, though for a good person someone might possibly dare to die. [SUP]8 [/SUP]But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.
1 John 4:71-12 [SUP]7 [/SUP]Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God. [SUP]8 [/SUP]Whoever does not love does not know God, because God is love. [SUP]9 [/SUP]This is how God showed his love among us: He sent his one and only Son into the world that we might live through him. [SUP]10 [/SUP]This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins. [SUP]11 [/SUP]Dear friends, since God so loved us, we also ought to love one another. [SUP]12 [/SUP]No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us.
Being forgiven and having a relationship with God shows us the depth of his love for us and from this outflows our love to God and others.
The other passage which shows us what love should look like is in 1 Cornithians 13
[SUP]4 [/SUP]Love is patient, love is kind. It does not envy, it does not boast, it is not proud. [SUP]5 [/SUP]It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. [SUP]6 [/SUP]Love does not delight in evil but rejoices with the truth. [SUP]7 [/SUP]It always protects, always trusts, always hopes, always perseveres.
[SUP]8 [/SUP]Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away. [SUP]9 [/SUP]For we know in part and we prophesy in part, [SUP]10 [/SUP]but when completeness comes, what is in part disappears. [SUP]11 [/SUP]When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put the ways of childhood behind me. [SUP]12 [/SUP]For now we see only a reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known.
[SUP]13 [/SUP]And now these three remain: faith, hope and love. But the greatest of these is love.
I know that phenylethylamine, norepinephrine, dopamine, oxytocin and serotonin are all chemicals released during attraction, infatuation, etc. Partly due to being a pharmacy technician, partly due to college, and partly due to google...but then I also remember hearing a presentation about two other chemicals released only during physical intimacy that also made couples have a stronger chemical connection.
I forgot what they were called, but it was explained as what makes a woman trust a man who may be a total jerk, and a guy want to stay with/protect a woman who might be using him/treating him terribly. There are actually chemical contributions to why that is if that couple is not celibate. Not necessarily information for this subject specifically, but interesting nonetheless.
Nice list of neurotransmitters. I used to work on oxytocin not in the sence of love but todo with blood vessels. Oxytocin is released during tough etc and makes you bond. It is released during labour and breast feeding and helps the mother bond with her new born child. Many women when they have given birth they feel an overwhelming feeling of love.
