Respectfully, yours is your reasoning read by you into the passages.
You write that you "concluded by reading the Bible ___."
That is just your mind on those things.
At the same time, some of it does appear to be based on truth to some degree and as a result, we will agree on those parts of it that are.
Like your conclusion that the Law is good and is profitable in Evangelism.
But then you go south with that. For the fact of the matter is, that this side of the instructions given by Christ through the Apostle Paul, "the law is
not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners," etc. 1 Tim. 1:9.
Fact of the matter is, that this side of His "having abolished in his flesh the enmity, even the law of commandments contained in ordinances;" Eph. 2:15 - in other words, by the sacrifice of Himself, verse 13, the reason "sin shall
not have dominion over you" will
not be due to keeping the Law, rather "sin shall
not have dominion over you:
for ye are
not under the law,
but under grace" Rom. 6:14.
In short, if you have trusted this here - 1 Corinthians 15's:
1. Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2. By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4. And that he was buried, and that he rose again the third day according to the scriptures:
If you have trusted that (I don't know, as I don't know if you have or have not) then this here applies to you - 2 Corinthians 5's:
21. For he hath made him to be sin for us, who knew no sin;
that we might be made the righteousness of God in him.
If you have trusted that (hopefully you will say you have) then your instruction is not the Law, as it is
'not for a righteous man," rather, Grace is now your teacher.
How do I know? Titus 2:
11. For the grace of God that bringeth salvation hath appeared to all men,
12. Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world;
13. Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ;
14. Who gave himself for us, that he might redeem us
from all iniquity, and purify unto himself a peculiar people, zealous of good works.
You see that, He gave Himself that by that He might redeem you that believe from
all iniquity.
That is the Grace of God that hath appeared unto all men - note Eph. 2 on this Grace in Christ Jesus:
1. And you hath he quickened, who were dead in trespasses and sins;
2. Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
3. Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
4. But God, who is rich in mercy, for his great love wherewith he loved us,
5. Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved; )
6. And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
7. That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus.
8. For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9. Not of works, lest any man should boast.
10. For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
In other words, He "gave himself for us, that he might redeem us
from all iniquity, and purify unto himself a peculiar people, zealous of good works.
Now here is the key - the being zealous of good works is not based on the Law for we "are no longer under a schoolmaster," Gal. 3:25.
Rather, the zealousness, the motivation is Grace motivation - note Titus 2 again:
11. For
the grace of God that bringeth salvation hath appeared to all men,
12.
Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world;
13. Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ;
14. Who gave himself for us, that he might redeem us
from all iniquity, and purify unto himself a peculiar people, zealous of good works.
And this is a theme throughout Romans thru Philemon, this Grace Motivation, this Grace Attitude or Gratitude that God's goodness in His kindness and His Grace in His Son toward us when we least deserved it, is mean to motivate good works in us.
Thus, Galatians 5's:
1. Stand fast
therefore in the liberty wherewith Christ hath made us free, and be
not entangled
again with the yoke of bondage.
2. Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing.
3. For I testify again to every man that is circumcised, that he is a debtor to do the whole law.
4.
Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
5. For we
through the Spirit wait for the hope of righteousness by faith.
6. For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith
which worketh by love.
You see that - it is faith empowered into action (good works) within our inward man by the love of Christ as we contemplate His sacrifice.
Neither a work, or no work at all, can bring the Believer closer to God's absolute and complete acceptance before Him than a Beleiever already is - in - His - Son!
I mean look at this - look at it - Galatians 3:
1. O foolish Galatians, who hath bewitched you, that ye should not obey the truth, before whose eyes Jesus Christ hath been evidently set forth, crucified among you?
2. This only would I learn of you, Received ye the Spirit by the works of the law, or by the hearing of faith?
3. Are ye so foolish? having begun in the Spirit, are ye now made perfect by the flesh?
Galatians 2:
19. For I through the law am dead to the law, that I might live unto God.
20. I am crucified with Christ: neverthless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
21.
I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.
The Law called for putting you to death!
Christ stood up in your stead.
Quit trying to frustrate the grace of God by these Law notions of yours - so you can get to rejoicing for all, and in all this grace wherein you can stand before God, at peace with Him, in His Son, by the Spirit, Romans 5:1, 2.
By the way, thank you for the opportunity to rejoice in all this once more that answering you based on 1 Cor. 15: 1-4 in light of 2 Tm. 2:15 has resulted in, in my inward man
Sincerely
