Here’s the contradiction I see:
>>No one is saved without forgiveness.
>> only if we confess our sins “he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.”
It would seem, in OSAS, that we presume that: either we will confess all future sins or we will be saved without forgiveness.
We are cleansed from ALL unrighteousness.
We CANNOT be perfect, even once we are saved. When we are saved we are transferred into the kingdom of the Son he loves. We are seated with Christ in the heavenly places.
God chooses to credit our account with the righteousness of Christ so when He sees us, he sees the righteousness of Christ.
It's a legal transaction but not one contingent on our faithfulness or our ability to uphold it but HIS.
