Yes, we are saved, and Paul says that that salvation is like the Jews' salvation from Egypt--yet they sinned and fell under God's wrath and forfeited the promise.
1 Co 9:27 - 1 Co 10
27But I discipline my body and keep it under control, lest after preaching to others I myself should be disqualified.
1For I do not want you to be unaware, brethren, that our fathers were all under the cloud and all passed through the sea;
2and all were baptized into Moses in the cloud and in the sea;
3and all ate the same spiritual food;
4and all drank the same spiritual drink, for they were drinking from a spiritual rock which followed them; and the rock was Christ.
5Nevertheless, with most of them God was not well-pleased; for they were laid low in the wilderness.
6Now these things happened as examples for us, so that we would not crave evil things as they also craved.
7Do not be idolaters, as some of them were; as it is written, “THE PEOPLE SAT DOWN TO EAT AND DRINK, AND STOOD UP TO PLAY.”
8Nor let us act immorally, as some of them did, and twenty-three thousand fell in one day.
9Nor let us try the Lord, as some of them did, and were destroyed by the serpents.
10Nor grumble, as some of them did, and were destroyed by the destroyer.
11Now these things happened to them as an example, and they were written for our instruction, upon whom the ends of the ages have come.
12Therefore let him who thinks he stands take heed that he does not fall.
13No temptation has overtaken you but such as is common to man; and God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will provide the way of escape also, so that you will be able to endure it.
That said, there is a stipulation that "fear has to do with torment" (1 J 4:18), and that fear characterizes the "slavery" of those "under Law" (Ro 8:15; Gal 4:23,24), and that "the Law is weakened through the flesh" (Ro 8:3; Gal 3:3), so that even correctly understanding all of these truths about how we must do good works after salvation can still lead to an incorrect conclusion that we should serve fearfully, in which case God will not work (Deut 32:26,27; Judges 7:2+) but leave us to the flesh which we are leaning on which will not lead to acceptable righteousness.
