The Psalmist wrote, "the Lord looked down from heaven at mankind to see if there are any who are wise, any who worship him. But they have all gone wrong; they are all equally bad. No one of them does what is right, not a single one." (Psalm 14:2,3)
As far as separating familes,
I have come to bring fire on the earth, and how I wish it were already kindled! But I have a baptism to undergo, and how distressed I am until it is completed! Do you think I came to bring peace on earth? No, I tell you, but division. From now on there will be five in one family divided against one another, three against two and two against three. They will be divided, father against son and son against father, mother against daughter and daughter against mother, mother-in-law against daughter-in-law and daughter-in-law against mother-in-law" (Luke 12:49-53)
Is that correct or do the nonchristian children go to Hell forever too?
