Matthew 25 (separation of the sheep and the goats) is pretty much the only time Jesus straight-up threatens people with Hell, and he’s basing it on the treatment of the poor, sick, and social outcasts.
5 Now listen, you rich people, weep and wail because of the misery that is coming on you. 2 Your wealth has rotted, and moths have eaten your clothes. 3 Your gold and silver are corroded. Their corrosion will testify against you and eat your flesh like fire. You have hoarded wealth in the last days. 4 Look! The wages you failed to pay the workers who mowed your fields are crying out against you. The cries of the harvesters have reached the ears of the Lord Almighty. 5 You have lived on earth in luxury and self-indulgence. You have fattened yourselves in the day of slaughter.[a] 6 You have condemned and murdered the innocent one, who was not opposing you.
