For some people the love of Christ or other form of spiritual love is the strongest they'll ever get. They have been abandoned, abused, neglected. They learn that trust leads to pain and earthly love is the worst source of pain. So how can they tap into the kind of love that keeps the atheist so happy? They need people with enough love and patience to reach them and often those people will be from a religious group or mental health professionals. They may be addicts, homeless, scarred inside and out. Their faith is the last thing between them and deciding not to live at all... so can we stop attacking each other's sources of love?
I believe the luckiest people of all have both, but not in the weak way advertisers push. They love their partners like lions and embrace their spirituality with passion. Don't let a mortal love stop you seeking divine love and don't be so satisfied with divine love that you neglect mortal love. For in truth, all love is immortal, it stretches, it bends, but it never ends. It does not obey mathematics for when it divides it multiplies. The wise person seeks all kinds of love - the Godly kind, a true lover and true friends/siblings. Why say stop? Why not let more in?
