Four levels of love

I think the 13th commandment contains an implied response to somebody's love, that is, receive that love. There's a reason why I say this: one of the things that makes it difficult to love [again] is when love is rejected. Rejected love helps some people love less or not at all when the next loving opportunity comes up. (Of course, we are always supposed to carry on loving, but that is the subject of another entry.)

So we have four levels of love:
(1) You love him/her.
(2) Him/her accept you's love.
(3) Him/her love you.
(4) You accept him/her's love.

A little confused? Paul helps us out with this one by saying:
'Accept one another, then, just as Christ accepted you, in order to bring praise to God.' (NIV)
Romans 15:7.
And he says that for the purpose of endurance, encouragement, unity and the like...
