Amazing grace - how broken the bound

How did we miss this?! We are wretched sinners no more. Why do we keep repenting when his offering was enough and when he remembers our sins no more? It sounds like heresy but could this really be?

Heb 10:14-17 (AMP):
14For by a single offering He has forever completely cleansed and perfected those who are consecrated and made holy. 15And also the Holy Spirit adds His testimony to us [in confirmation of this]. For having said, 16This is the agreement (testament, covenant) that I will set up and conclude with them after those days, says the Lord: I will imprint My laws upon their hearts, and I will inscribe them on their minds (on their inmost thoughts and understanding), 17He then goes on to say, And their sins and their lawbreaking I will remember no more.

It is because of many many years of misinformed teaching that we read past this! Why would the Lord in his awesome glory only forgive our past sins? Is he not beyond time? Do you think that your new sin is a surprise to him? Did he not know when he was on that cross?

Yes all of us sinned and none were perfect (as it says in the book of Romans), so that nobody can say that they earned right-standing with God!

When I found this out everything started to make sense to me. If we were born into sin, then being born again means that we get born into righteousness. See this:

2 Corinthians 5:17,21 (AMP):

17Therefore if any person is [ingrafted] in Christ (the Messiah) he is a new creation (a new creature altogether); the old [previous moral and spiritual condition] has passed away. Behold, the fresh and new has come!

21For our sake He made Christ [virtually] to be sin Who knew no sin, so that in and through Him we might become [[a]endued with, viewed as being in, and examples of] the righteousness of God [what we ought to be, approved and acceptable and in right relationship with Him, by His goodness].

How amazing! God is so good.

Why do we keep quiet in church when somebody calls the righteousness of God a wretched sinner? Perhaps because we might be stoned to death or something!
