Dearest Inkie... the greatest of love and peace to you, my brother... and may I say:
Very simply put, and... amen and amen.
It is indeed quite a simple thing that is required, isn't it? My Lord in fact made it simple by SHOWING us how we are to walk: he loved his brothers (and DEMONSTRATED this love by helping/feeding/healing/teaching ALL who came to him, even when they weren't Israel, although that was the only "house" he had been sent to)...as well as "loved" his enemies...and DEMONSTRATED that love...for he did not return evil for evil or go reviling, even offering the gift of "living water" to the Samaritan woman (an "enemy" of Israel), as well as healing the servant of the [Roman] Army office and the daughter of the Phoenician woman.
Is it so much to ask of us, those who claim to be "christian" to love one another? No, and we do it all the time. But so do "the nations". It is when we learn to love our enemies... to love those who do NOT love us... that we can "prove" ourselves sons of our heavenly Father. And we CAN do it... in SPITE of what we've "heard it said" by earthling to do under the guise of "godly devotion".
As always, much peace to you!
Your servant, sister, and fellow slave of Christ,
SJ
