Love unconditionally just as Jesus loves us. If we don't love, TRULY LOVE, others no matter who they are, what they believe, or what they've done... We aren't following Christ. Make it clear where you stand, but don't condemn.
As a Christian, I may not agree or be for someone's else's beliefs or ways of life but that doesn't mean not to love them. Love thy neighbor as yourself right? Yes!! But lots of times people make disagreement and hate looked as the same and it isnt!! I might not agree with you but that's no excuse bot to love you or treat you like I would wanna be treated!
"Do not waste time bothering whether you 'love' your neighbor; act as if you did. As soon as we do this, we find one of the great secrets. When you are behaving as if you loved someone, you will presently come to love him." -C. S. Lewis
