No. Non-christians are not capable of love. They have some vague idea of what love is supposed to be, but that's as far as it goes. Love is a fruit of the Spirit. John also said Love is of God because God is Love. That being said, it is impossible for an unredeemed person to have love, because they don't have God.
The closest an unsaved person comes to love is lust.
Hmm. Good point. Yes, oyoure right. No, they can not. Jesus is LOVE. Without Him, then you dont have love.
