Are atheists truly "free"?
2 Peter 2:11 Whereas angels who are greater in strength and power, bring not against themselves a railing judgment. 12 But these men, as irrational beasts, naturally tending to the snare and to destruction, blaspheming those things which they know not, shall perish in their corruption, 13 Receiving the reward of their injustice, counting for a pleasure the delights of a day: stains and spots, sporting themselves to excess, rioting in their feasts with you: 14 Having eyes full of adultery and of sin that ceaseth not: alluring unstable souls, having their heart exercised with covetousness, children of malediction: 15 Leaving the right way they have gone astray, having followed the way of Balaam of Bosor, who loved the wages of iniquity, 16 But had a check of his madness, the dumb beast used to the yoke, which speaking with man's voice, forbade the folly of the prophet. 17 These are fountains without water, and clouds tossed with whirlwinds, to whom the mist of darkness is reserved. 18 For, speaking proud words of vanity, they allure by the desires of fleshly riotousness, those who for a little while escape, such as converse in error: 19 Promising them liberty, whereas they themselves are the slaves of corruption. For by whom a man is overcome, of the same also he is the slave.
One can only be free with the truth.
John 8:32 And you shall know the truth, and the truth shall make you free.
What is truth? Quid est veritas?
John 14:6 Jesus saith to him: I am the way, and the truth, and the life.
