Is a believer TODAY saved by justification or sanctification ?
Gawd.
So what's your answer ? Jus or San, which one ?
Double gawd.
The question, 'was can a believer who is justified lose that justiification?'
Yes a believer can.
An additional question is 'can a believer who is sanctified lose that sanctification?'
Yes a believer can.
Because Paul tells us a believer who is sanctified can lose sanctification, it stands to reason that a believer who is justified can lose justification because you claim once a believer is justified that believer goes through the sanctification process.
