I've been researching the subject a little bit and I'm confused. When Christians talk of 'our sins' are they talking about the Sin we're born with or the little sins/transgressions that we commit every day? When one is baptised, christened.etc is it our inherited sin we're washing away alone or is it our Sin and our little sins or is it just our little sins and not our inherited Sin?
The apostle Paul described his state (after his conversion) in the book of Romans. He described it as indwelling sin, he noticed that he was doing things he didn't want to do.
Romans 7:19-25 King James Version (KJV)
19 For the good that I would I do not: but the evil which I would not, that I do.
20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
21 I find then a law, that, when I would do good, evil is present with me.
22 For I delight in the law of God after the inward man:
23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
24 O wretched man that I am! who shall deliver me from the body of this death?
25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
Paul makes it clear that we will continue to sin until the day we die, but we don't sin in a unrestrained manner as we did before our conversion.
Unconverted people, don't mourn or grieve over their sin as believers do. Jesus eluded to this in His sermon on the mount, when He said "blessed are the poor in spirit".
As followers of Christ, we can't enjoy sin any longer and the more "Christ like" we become the more we hate sin.
So we will continue to wrestle against our "flesh", until we receive our glorified sinless bodies in the life to come.
