1 Corinthians 9:27 says:
“But I keep under my body, and bring
it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.”
First, here are some verses that say a similar thing.
Romans 8:13
“For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.”
James 1:12
“Blessed
is the man that endureth temptation: for when he is tried, he shall receive the crown of life, which the Lord hath promised to them that love him.”
James 1:21
“Wherefore lay apart all filthiness and superfluity of naughtiness, and receive with meekness the engrafted word, which is able to save your souls.”
2 Corinthians 7:1
“Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.”
Second, in context, 1 Corinthians 10 says,
1 Corinthians 10:1-12
1 “Moreover, brethren, I would not that ye should be ignorant, how that all our fathers were under the cloud, and all passed through the sea;
2 And were all baptized unto Moses in the cloud and in the sea;
3 And did all eat the same spiritual meat;
4 And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.
5
But with many of them God was not well pleased: for they were overthrown in the wilderness.
6
Now these things were our examples, to the intent we should not lust after evil things, as they also lusted.
7 Neither be ye idolaters, as
were some of them; as it is written, The people sat down to eat and drink, and rose up to play.
8 Neither let us commit fornication, as some of them committed, and fell in one day three and twenty thousand.
9 Neither let us tempt Christ, as some of them also tempted, and were destroyed of serpents.
10 Neither murmur ye, as some of them also murmured, and were destroyed of the destroyer.
11
Now all these things happened unto them for ensamples: and they are written for our admonition, upon whom the ends of the world are come.
12
Wherefore let him that thinketh he standeth take heed lest he fall.”
Paul says we are not to have fellowship with any brother who is a fornicator, covetous, an idolater, drunkard, etcetera.
1 Corinthians 5:9-11
“I wrote unto you in an epistle not to company with fornicators: Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world. But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat.”
So no believer could ever have fellowship with each other if OSAS was true.
The idea here is that if a believer was in sin, they would be cast out with the world until they confessed of their sins and forsaken them.
So your excuse to undo what Paul said in that he is speaking hypothetically is null and void, friend.
1 Corinthians 9:27 means what it says plainly. Paul says he can be a cast away and he literally means that. You simply do not like what he said, and so you are attempting to come up with an excuse to explain his words away (Which runs contrary to the context and the rest of the Bible).
