In Galatians 3:14, we find that we receive the Holy Spirit through faith in Jesus Christ.
In Galatians 5:22-23, we find that if anyone bears the fruit of the Spirit (which is love, the bond of perfectness, Colossians 3:14), that there is no law in existence that will condemn their behaviour.
In other words, those who bear the fruit of the Spirit become law-abiding citizens of the kingdom of heaven.
It is a righteousness apart from the law that is nevertheless attested to by the law and the prophets that it is righteousness indeed (Romans 3:21).
Because we do not obtain this righteousness through attempting to obey a set of do's and don'ts.
The righteousness of the law is fulfilled in those who walk not after the flesh but after the Spirit (Romans 8:4).
The one who is born of God "cannot sin" (1 John 3:9) and the one who doeth the will of God abideth ("sinneth not", 1 John 3:6) for ever (1 John 2:17).
I do believe that if someone is not circumcised of heart (i.e. they have not yet been perfected in their walk), that righteousness is still imputed to them if they have faith in Jesus Christ (Romans 4:11).
But why would anyone who has the Holy Spirit want to continue to live a lifestyle that is characterized by Romans 7:14-25? According to Romans 7:24, the attitude of someone in that state who is born again or about to become born again, is that they are discontented with such a lifestyle.
I may not seek entire sanctification because of the possibility of condemnation if I do not obtain that benefit. But I might seek it because of the "chastening of the Lord"...in that my conscience afflicts me when I don't measure up to what the Lord desires for me in the way of holiness. I am discontented with being in such a state; and therefore the doctrine of entire sanctification is good news to me (found in such verses as 1 Thessalonians 5:23-24 (kjv), Hebrews 10:14 (kjv), 1 John 3:9; 1 John 3:7, 1 John 3:3, 1 John 2:6; Jude 1:24, 2 Peter 1:10, 1 John 2:10; 1 John 3:6, 1 John 2:17; Romans 6:6 (kjv), Colossians 2:11 (kjv), (NLT)).
And there is the possibility that those who have not received the second benefit are not saved at all. I know that Bible scholars more intelligent than myself have made that conclusion.
So, why would anyone want to take a chance on the idea that they can make it into the kingdom of heaven apart from entire sanctification? While there are verses that might seem to say that I can have righteousness imputed to me apart from that benefit, they do not present an airtight case for that concept.
