John 8:34, 36

Jesus answered them, Truly, truly, I say to you, Everyone practicing sin is a slave of sin.

Therefore, if the Son sets you free, you are free indeed.

2 Peter 2:18-19, 10-17

For speaking over-swollen words of vanity, by the lusts of the flesh, by unbridled lusts, they allure those indeed escaping, the ones walking in error,

promising to them freedom, though themselves being slaves of corruption; for by whom anyone has been overcome, even to this one he has been enslaved.

and most of all those going after flesh in the lust of defilement, and despising rulership, darers, self-pleasing; they do not tremble at glories, speaking evil;

where angels being greater in strength and power do not bring against them a reproaching charge before the Lord.

But these as unreasoning natural beasts, having been born for capture and corruption, speaking evil in that of which they are ignorant, they shall utterly perish in their corruption,

being about to receive the wages of unrighteousness, having deemed indulgence in the day to be pleasure; spots and blemishes reveling in their deceits, feasting along with you,

having eyes full of an adulteress, and never ceasing from sin; alluring unsettled souls; having a heart being busied with covetousness; cursed children;

forsaking a straight path, they went astray, following the way of Balaam the son of Beor, who loved the wages of unrighteousness,

but had reproof of his own transgression, the dumb ass speaking in a man's voice held back the madness of the prophet.

These are springs without water, clouds being driven by tempest, for whom the blackness of darkness has been kept to the ages.
