Why did Paul write not of works, lest anyone should boast ?
Because in that time many considered themselves under the Mosaic Law, that you could earn your salvation by works. And Paul said no, it's only by God's Grace, only because of Jesus, no more boasting. See that?
- By grace.
- Through faith.
- Repentance.
We are saved, we receive the indwelling Holy Spirit to guide us through all the temptations of our sinful flesh. Everything after that is conditional. Do we stumble, there is forgiveness, always, as long as we abide in Christ and overcome. However if we decide to live by the flesh we lose our salvation -- Romans 8:1-11
"Because in that time many considered themselves under the Mosaic Law..." This is not stated in the text of
Ephesians 2, nor is it implied. In fact, in the first and second chapter of Paul's letter to the Ephesian believers, there isn't a single mention of the law of Moses. But Paul does, in
chapter 2, indicate to whom he is directing his words:
Ephesians 2:11-13
11 Therefore remember that you, once Gentiles in the flesh—who are called Uncircumcision by what is called the Circumcision made in the flesh by hands—
12 that at that time you were without Christ, being aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God in the world.
13 But now in Christ Jesus you who once were far off have been brought near by the blood of Christ.
It is evident in what Paul wrote here that those in view in
chapter 2 are not Jews wanting to keep the Mosaic Law but
Gentiles, those of the uncircumcision, aliens from the commonwealth of Israel. So, then, what does Paul mean by "good works"? Since his words aren't directed at Jews but at Gentiles, he would not have been referring to the Mosaic Law about which Gentiles would have been quite unconcerned. No, instead, Paul was speaking generically of good deeds done to garner acceptance with God. Such deeds he completely excludes as a means of one's salvation so that "no one may boast" in their having earned, or deserved, God's
free gift of salvation in and through Jesus Christ.
"We are saved, we receive the indwelling Holy Spirit to guide us through all the temptations of our sinful flesh."
Yes, we are saved when we receive the Holy Spirit, who makes of us his "temple," bought with the precious blood of Christ (
1 Co. 6:19-20). His life and work in us transforms us, making us into "living letters of Christ (
2 Co. 3:3).
"However if we decide to live by the flesh we lose our salvation -- Romans 8:1-11"
Nowhere in all of
Romans 8 does Paul ever write anything like what you have written here. In the early portion of the chapter, Paul describes two kinds of people: The fleshly-minded person and the Spirit-minded person. Not once in the first 16 verses of the chapter does Paul ever even imply that a saved, Spirit-minded person could become a lost, carnal person.
Funny that you posted this verse in defense of OSAS, it's an example OSAS is wrong, the Galatians started from Grace and then fell from Grace, Paul calling for repentance.
I'm afraid this just demonstrates how unfamiliar you are with Paul's epistle to the believers in the province of Galatia. "Fall from grace" does not mean "lose salvation." This is an interpretation of the phrase that you're imposing on it, not drawing out of it. In context, "fall from grace" refers to the Galatian believers trying to achieve God's acceptance by way of law-keeping. They began with God by the cleansing, spiritually-regenerating work of the Holy Spirit (
Tit. 3:50), not by fleshly law-keeping into which Judaizers had been urging them to move (
Ga. 3:3). All throughout the letter to the Galatian believers, Paul contrasts law-keeping with grace, making it as clear as he could that acceptance with God was by grace, through faith, entirely apart from good works. See:
Galatians 1:6-7; 2:4-5, 11-17; 3-6.
Galatians 5:1-6
1 Stand fast therefore in the liberty by which Christ has made us free, and do not be entangled again with a yoke of bondage.
What is the liberty of which Paul wrote here? Liberty from the burden and death of law-keeping. Against this "yoke of bondage" Paul urges his readers to "stand fast," refusing the urgings of the Judaizers among them.
2 Indeed I, Paul, say to you that if you become circumcised, Christ will profit you nothing.
Here is what Paul meant by "fall from grace": Christ will profit nothing." Not, "Christ will reject you." Not, "Christ is lost to you." Not, "Christ will no longer save you." What does it mean that "Christ will profit you nothing"? Well, if I own a lawnmower but resort to trimming my lawn with a pair of eye-brow tweezers, my lawnmower ceases to be of profit, or benefit, to me. Does my using tweezers mean I no longer possess my lawnmower? No, of course not. In the same way, if I try to live the Christian life using the "tweezers" of law-keeping, I don't cease to possess the "lawnmower" of saving grace in Christ Jesus. I simply take up the impossible (and ridiculous) task of making myself acceptable to God by "tweezing" the "grass" of my life with law-keeping. This is a ridiculous thing to do precisely because I posses the "lawnmower" of life in Christ Jesus but refuse to benefit from its power to "cut the grass" of my life.
3 And I testify again to every. man who becomes circumcised that he is a debtor to keep the whole law.
Here, Paul explains why law-keeping is a stupid thing to try to do to gain acceptance with God. One must keep the whole law perfectly, all the time, which cannot be done - as the record of the OT makes amply clear.
4 You have become estranged from Christ, you who attempt to be justified by law; you have fallen from grace.
Estrangement is not the same as divorcement, or the utter dissolution of a relationship. See
Luke 15:11-32.
In context, Paul means that the ones who has "fallen from grace" cease to benefit from the grace of Christ in their life as God's child. They possess Christ (and are possessed by him) but this fact doesn't profit them spiritually because they've taken up the "tweezers" of law-keeping.
5 For we through the Spirit eagerly wait for the hope of righteousness by faith.
On what basis does Paul say the Christian "eagerly waits for the hope of righteousness by faith"? On the basis of obedience to God? On the basis of law-keeping? No. He wrote that it was "
through the Spirit" that they could eagerly anticipate "the hope of righteousness by faith." Without the regenerating, transforming life and work of the Holy Spirit, righteousness by faith would be a hopeless thing. See:
Jn. 14:26; 16:8, 13; Ro. 8:9-16; 1 Co. 2:10-16; 2 Co. 3;18; Eph. 3:16; 6:10; Phil. 2:13; 4:13; Ga. 5:16, 25, etc. The only righteousness that God will accept is that which arises from
His own Spirit within the believer. All else is fleshly law-keeping which God rejects.
6 For in Christ Jesus neither circumcision nor uncircumcision avails anything, but faith working through love.
And both this faith and love must be of God, of the Holy Spirit, more precisely, which He gives to His children.
Romans 5:5
5 Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us.
Romans 12:3
3 For I say, through the grace given to me, to everyone who is among you, not to think of himself more highly than he ought to think, but to think soberly, as God has dealt to each one a measure of faith.
Our salvation is entirely of God and what follows beyond the point of conversion is also entirely of Him. We are merely the joyful recipients of His life and work in us, vessels of grace - if we don't migrate into fleshly attempts to earn God's gift of acceptance of us.
Galatians 3:3
3 Are you so foolish? Having begun in the Spirit, are you now being made perfect by the flesh?
