To go back to the OP, I believe that Paul defines the perspective when he says:
Rom 6:11 Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
God is doing the work, but unless we by faith reckon ourselves to be partakers, it is of no effect.
It is very much like the attitude difference between those who continue to refer to believers as "sinners saved by grace", with full expectation to continue to fall or those who embrace the teaching of the NT that we are already "saints".
As I have said before, this does not make us sinless, but it does enable us to sin less.
Jesus died not just to deliver us from the penalty of sin, but also the power of sin.
1Jn_3:8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
The oft misunderstood passage of I Jn 2:1 says this:
1Jn 2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
John says, "IF", not "when", which is the mistake and mentality of those who choose to continue to refer to themselves as sinners saved by grace.
We
were sinners, but now we are saints! We have been separated from sin and consecrated unto God.
Rom 6:11 Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
