John 8:34 says, “…Most assuredly, I say to you, whoever commits sin is a slave to sin.” Verse 36 says, “Therefore if the Son makes you free, you shall be free indeed.”
Romans 6:1-2 says, “What shall we say then? Shall we continue in sin that grace may abound? Certainly not! How shall we who died to sin live any longer in it?”
Verse 4 says at salvation, “Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also shall walk in newness of life.”
Verse 7 restates it saying, “For he who has died has been freed from sin.” Verse 16 gives us a choice. It says, “…to whom you present yourselves slaves to obey, you are that one’s slaves whom you obey…”
The context of 2 Peter is about false teachers and destructive doctrines.. 2 Peter 2:19 says, “…for whom a person is overcome, by him also he is brought into bondage.” Warning: do not return to what you were freed from.
