Friend, I am just a beggar telling another beggar where to find bread.
"Love one another" is the very law that we cannot keep perfectly and therefore subjects us to the guilt and punishment of sin. This puts us at enmity with God--who, though a God of Love, is also a God of Justice (he is Holy).
Peace between God and men required the sacrifice of Christ to reconcile us to him.
The gospel (good news) of grace is that Christ loved perfectly *for us* and we can therefore escape just punishment and enter glory. This he did "while we were still enemies."
This is the Love and Peace that God brings through Christ, our redeemer.
One might reject this teaching, but at least understand what Christianity is before doing so... peace my friend, really like your posts!
