Faith saves us from sin.
They know they are sinning and do/did so anyway:
Romans 1:18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. 19 For what can be known about God is plain to them, because God has shown it to them. 20 For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.
Asking again. It has to be Justice that those departed Asians end up in the lake of fire, since they didn’t believe in Jesus, and God set the penalty. Do you agree?
