There are no “hard people”

Among humanity, is no pre-disposition towards saving grace, only pre-indisposition. If we are "dead in our trespasses and sins", then nobody is "farther" or "closer" away from Christ. We are all, rather, equally dead. The ground is level both at the foot of the cross and the plain of the cemetery. Nobody is more saved than others by Christ and nobody is more separated than others from Christ. So Saul the persecutor of Christians and Cornelius the "God-fearer" were equally dead in their trespasses and sins and equally in need of divine alien righteousness. And this makes all the difference for how we make disciples among the nations.
