Just wanting to start a thread...lolz.
But really...If you warn the world not to go to hell and instead choose heaven...most will choose heaven. Due to the fact of self-preservation as paul washer says. I think The Best and most effective way to evangelize is to build relationships with people..And show them and tell them that their life of sin will not satisfy them and never will and only jesus will satisfy them. And simply being the best walking buildboard for christ we can be. Letting God daily mold us and shape us into his son jesus chrsit
