How do you trust and love in today’s world that is so full of mistrust & relationship game playing?

I’ve learned that people are going to either love or hate, play or get serious. I understand there is a fight against darkness and in the fight light always wins. I also understand that nothing outside of the promise of God is promised. I put my trust in God -in doing that I can live freely, love freely without worrying about the way of the world or joining the darkness, the game playing or intentionally hurting others.
