That approach is a sure approach to the Lake of Fire. For you do not obey. The approach of salvation is "God be merciful to me a sinner."
It is hopeless to trust in one's own good works, which are obediences to the Lord. Men are disobedient & merit the Lake of Fire for it. The wages of sin is death. Moreover, it is not in the nature of sinful man to obey. A new birth is required to change the nature. The only obedience which saves (from man's POV) is obedience to this command:
Believe on the Lord Jesus, and you shall saved.
Salvation requires rest from self-righteous supposed good works, and trusting the Savior to do His job, that of saving:
Heb 5:9 does not support your theory at all. Here it is with context:
To-day if ye shall hear his voice,
8 Harden not your hearts, as in the provocation,
. . .
10 Wherefore I was displeased with this generation,
And said, They do always err in their heart:
But they did not know my ways;
11 As I sware in my wrath,
They shall not enter into my rest.
12 Take heed, brethren, lest haply there shall be in anyone of you an evil heart of unbelief, . . .
to whom sware he that they should not enter into his rest, but to them that were disobedient? 19 And we see that they were not able to enter in because of unbelief.
4:1 Let us fear therefore, lest haply, a promise being left of entering into his rest, any one of you should seem to have come short of it. 2 For indeed we have had good tidings preached unto us, even as also they: but the word of hearing did not profit them, because it was not united by faith with them that heard. 3 For
we who have believed do enter into that rest; even as he hath said,
As I sware in my wrath,
They shall not enter into my rest:
although the works were finished from the foundation of the world.
4 For he hath said somewhere of the seventh day on this wise, And God rested on the seventh day from all his works; 5 and in this place again,
They shall not enter into my rest.
6 Seeing therefore it remaineth that some should enter thereinto, and they to whom the good tidings were before preached failed to enter in because of disobedience,
[When anyone fails to trust the Lord for salvation, that man is in disobedience to the one command that he must obey for salvation: Believe . . . & be saved.]
. . .
There remaineth therefore a sabbath rest for the people of God. 10 For
he that has entered into his rest hath himself also rested from his works, as God did from his. 11 Let us therefore give diligence to enter into that rest,
[To trust Christ as Savior is a command, & the command includes resting from your works]
that no man fall after the same example of disobedience. . . .
Let us therefore draw near with boldness unto the throne of grace, that we may receive mercy, and may find grace to help us in time of need. . . .
7 Who in the days of his flesh, having offered up prayers and supplications with strong crying and tears unto him that was able to save him from death, and having been heard for his godly fear, 8 though he was a Son, yet learned obedience by the things which he suffered; 9 and having been made perfect, he became unto all them that obey him the author of eternal salvation; 10 named of God a high priest after the order of Melchizedek.
[The only obedience which saves is obedience to
"Believe on the Lord Jesus, and you shall be saved," which implies that you rest from your works and depend on Him alone -- Thou shalt call His name Jesus, for
He shall save His people from their sins.] . . .
but he, because he abideth for ever, hath his priesthood unchangeable. 25 Wherefore also he is able
to save to the uttermostthem that draw near unto God through him, seeing he ever liveth to make intercession for them.
26 For such a high priest became us, holy, guileless, undefiled, separated from sinners, and made higher than the heavens; 27 who needeth not daily, like those high priests, to offer up sacrifices, first for his own sins, and then for the sins of the people: for this he did once for all, when he offered up himself. . . .
