Jesus set the standard for our love and that is to treat others how we would want to be treated.
Luke 6:31 And as you would like and desire that men would do to you, do exactly so to them.
Although Jesus said how to love I think we tend to love not as we want to be loved, but how we were not loved. What I mean is we grow into this hard kind of person because of how we were treated. We have our guard up because we were hurt and in that pain we are incapable of loving as we were designed to love.
As His, Jesus is teaching how to live in His Kingdom, so our call is to break the cycle of pain, and change it to His kind of love.
We can do that by going to Him and getting healed and then turn around and love with His love. Because now we are healed and have no pain to give away, we can love. We can give away what Jesus gave to us, His love.
