I'm abit torn and I may rest in the fact that I don't fully understand yet but with the spilling of blood, there is no forgiveness of sin Heb 9:22, hence why there was a continual sacrifice of animals under the old covenant. Jesus on the other hand, His blood spilt and sacrifice is one and for all time... If we have to receive forgiveness from God every time we sin, whether intentionally or not, Jesus would have to spill His blood again to atone for it, or something would have to but obviously we know that Jesus' sacrifice is final.
My carnal wants to tell me you have to continually repent in order to receive forgiveness, it makes sense, that's how us humans deal with one another. But I feel it's different with Our Father, that's not saying I don't apologise and ask to God to forgive me when I screw up, but I think the forgiveness is somewhat 'automatic' for a lack of better words. As if He says, I know son, it's already done.
As I said, I don't quite understand as yet and could be wrong, but that's just some thoughts.
