When Christ was on the Cross dying .HE TOOK every sin of else no one living after it could be bought and paid for ..Every sin ...all the HORRID perversion..COVERED BY HIS BLOOD.
If His blood is NOT sufficient..Why are we here..
If we sin ..And we do ..we must repent ..He alone forgives,US and washes us CLEAN..with His blood..
As far as the east is from the west ..so far far has he removed our transgressions from us.
NOW,IF WE SIN and hurt others..we must as well as possible make our peace with them ..so as nit go sin further.
And we may also have penalties here in earth from our sins..
BUT AGAIN the Blood was sufficient...it else why was HE SACRIFICED.
WHAT GOOD WAS IT ..IF NOT TO PAY OUR DEBT .
Well it goes to a mindset of OSAS(Once Saved Always Saved)....
Often we take comfort in the "idea" that God did it all in order to offer salvation. And that once we believe the idea, then we are saved forever. If this were the case, then backsliding does not exist.(But we know it does.) And we know that we continue to sin even in our surety of our salvation.
Also it goes to the mindset of ORAR(Once Repentant Always Repentant).
This is more a false confidence we have that since we were repentant once to God, that we are always repentant.
God does not override our own wills, and so if we turn away from God after becoming a Christian, he allows us to go. Likewise if after we journey for awhile after turning away, we still can return, but there is a price to pay, since Jesus is not crucified twice. The price is purgation.
Perhaps you have not deviated from God since becoming a Christian? But I tend to think, the longer one is a Christian, one encounters spiritual warfare within themselves as God allows us to see our sinful nature. In seeing this nature we can turn(repent) and become closer to God, as He works within and with us....
