God didn't preserve His words to teach me about problems Paul was dealing with in the Corinth, he preserved His words to teach us that there is nothing new under the sun and the same problems that Paul dealt with there exist today albeit in different forms.
Really, where does Scripture say that? If people would listen to what the text says instead of telling it what it says there'd be a lot more unity in the Christian faith. Paul told the Corinthians that all that the Jews had gone through in the wilderness was an example for the Christian.
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. {followed...: or, went with them}
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. {our...: Gr. our figures}
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.

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. (1Co 10:1-11 KJV)
However, I you have not addressed the contradiction that your position creates with the Scriptures. Paul said that God will judge everyone according to their deeds. He said those who continue in well doing are seeking eternal life those who don't, indignation and wrath. This statement flatly contradicts the idea that works play no role in salvation. Likewise Jesus told the apostles, when speaking of entering the kingdom, to "strive" to enter in. To strive is to do things to accomplish a goal.
It's really sad that so many have bought into this Reformation teaching because it is so far from what the Scriptures teach. This idea didn't even enter the church until around the 1500's, that's over 1400 years after Christ. If a doctrine doesn't appear until 1400 years after the event it's pretty certain it's wrong.
