You know, that sounds like a lesser definition of sin because it’s unclear. But truthfully the bar just got raised. If a man is walking by the spirit, he will anticipate the needs of others way beyond the law. The old law won’t require you to share your lunch. The new law will. The old law doesn’t require kindness. The new law, the law of walking in the spirit not the (unkind) flesh does.)
So the standard is higher.
(Am in streetcar so I have a few minutes.)
It is, in a sense, a higher standard (see Matthew 5:20).
However, the paradox is found in that we cannot keep the lower standard perfectly (Galatians 6:13); while, if we have the Spirit, we can be obedient to the higher standard (Romans 8:4).
For example, the lower standard (the law of Moses) requires that I wear tassels on my garments in order to remind me to obey the law; which I find myself unable to keep because I do not know where to buy or how to make a garment with tassels (and I think that it is something also that is reminiscent of what the Judaizers were trying to do to the Galatians in Paul's day; so I think that even if I had access to tassels, I wouldn't wear them unless I in the same breath told people that I myself do not measure up to the standard of the law and used it as an opportunity to show them that they themselves are not keeping the law perfectly unless they can also do what I am doing in wearing those tassels; and that even with the tassels, there are other tenets in the law that they would have to be obedient to; such as blowing the chofar on every new moon).
While the standard of Romans 8:4 requires an inward change; which is indeed a higher standard which would be impossible to keep if not for the Holy Spirit coming to dwell within me and shedding His love abroad in my heart (Romans 5:5).
But because it is the Holy Spirit's work, it is easier, even though it is a higher standard; because the yoke of Jesus is easy and His burden is light (Matthew 11:28-30); while the yoke of the law is heavy and represents a burden that neither we nor our forefathers were able to bear (Acts 15:10).
Also, with the higher standard of walking after the Spirit rather than the flesh, it is impossible unless one has the Spirit to begin with.
Yet, if anyone has the Spirit, it is not a matter of striving but of resting in the grace of God.
My salvation rests on the fact that Jesus died in my place as a substitute: my sins were applied to His account as He took their penalty, and His righteousness, perfection, and blood, are applied to my account so that I now have access to heaven (i.e. the throne room of the Father, Hebrews 4:16).
As I trust that Jesus lived the perfect life that is applied to my account, I now no longer have to strive to keep from sinning but I can rest in the grace of Jesus and just be,
If, in that, it turns out that I am still a sinner, at least I know that I am not seeking to establish my own righteousness but am resting in the righteousness that is provided through the blood of Jesus as it is imputed to me (see Romans 10:3).
If, in that, it turns out that I am becoming more and more like Christ, then that is the work of the Holy Spirit in sanctification.
As it is written,
Pro 4:18, But the path of the just is as the shining light, that shineth more and more unto the perfect day.
But I find that Jesus can only live a perfect life; so if it is Jesus who is living His life in me and through me (see Galatians 2:20), then the life that is lived is going to be a perfect one.
It is only when I take back my life that I get into trouble. When I am the one who is doing the living, I am sure to sin.
The problem with a living sacrifice (see Romans 12:1-2) is that it has the tendency to crawl off the altar.
Thus it is written,
Psa 118:27, God is the LORD, which hath shewed us light: bind the sacrifice with cords, even unto the horns of the altar.
