Loving your Oikos into Heaven

What is love? And what does it mean to each of us?
Romantic love is not sustainable; filial love in friendship can have fallouts; the only perfect love is ‘agape’:
“I am giving you a new commandment, that you love one another. Just as I have loved you, so you too are to love one another. By this everyone will know that you are My disciples, if you have love and unselfish concern for one another.” (John 13:34-35)
This “new (and 11th) command” only appears 4 times in the Bible, mentioned by Apostle John (1 Jn 2:7, 8; 2 Jn 1:5). Commands are not a suggestion/proposal/recommendation; they are meant to be obeyed. Without this love, the Gospel cannot be preached to the ends of the earth.
