IF Jesus died for the whole world (Jn 3:16, et al), this passage has some pretty broad implications for how we see and treat anyone, not just believers; everyone is our brother and sister:
And so we know and rely on the love God has for us.
God is love. Whoever lives in love lives in God, and God in them. This is how love is made complete among us so that we will have confidence on the day of judgment: In this world we are like Jesus. There is no fear in love. But perfect love drives out fear, because fear has to do with punishment. The one who fears is not made perfect in love.
We love because he first loved us. Whoever claims to love God yet hates a brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen. And he has given us this command: Anyone who loves God must also love their brother and sister.
-- 1 John 4:16-21
The path of prayer is taken by those rare people who consciously and slowly let go of their ego boundaries, their righteousness, their specialness, their sense of being important.
-- Richard Rohr
