1 Corinthians 13:4-5: “Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs."
This I believe is a great start. Love is more than a concept of mankind, it is built into us. However we have our own ideas on it, we twist it, we manipulate it, we try to make it work for us. Love is not something we win, it's not something we always recieve, it is something we give. We give it because love is not something you can gain, or earn, it's something that someone chooses to give you freely. It's not love if it has conditions, that is something wicked and harmful. Love is hard to define, but easy to feel.
