Passage
Now I declare to you, brothers, the Good News which I preached to you, which also you received, in which you also stand,
Now I declare to you, brothers, the Good News which I preached to you, which also you received, in which you also stand,
1 Corinthians 15:1 Now I declare to you, brothers, the Good News which I preached to you, which also you received, in which you also stand,
1 Corinthians 15:2 by which also you are saved, if you hold firmly the word which I preached to you—unless you believed in vain.
1 Corinthians 15:3 For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures,
The verse centers on "declare", "brothers", "good", "news", "preached", "received", and "stand". It is saying that the verse draws attention to "declare" and "brothers", so its meaning should be read from those terms before moving to application.
The next verse adds "by which also you are saved if...", so "declare" and "brothers" should be read forward into that movement. In 1 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "declare" and "brothers" with trust shaped by these words, not by a vague optimism outside the passage.
