The biblical definition of gospel is literally GOOD NEWS! You are the one who is ignoring the biblical definition.
Look up the verse where it says the holy spirit convinced people of sin, righteousness and judgement. That’s HIS (their?) Job.
Now find me a verse where we are told to go put and spread the bad news first. Find the verse where we are directed to tell people about their own sin. You won’t find it.
You might find a verse DESCRIBING how someone did it, but you won’t find a verse PROSCRIBING it. This is known as the proscriptive fallacy.
That verse in 1cor15 is as close as you’re gonna get. Paul DESCRIBES how he received the gospel in a great-power incident. Pretty special circumstances—not everyone is blinded for 3 days when preached to , and his message was DIRECTLY from Jesus, not from other believers.
“The biblical definition of gospel is literally GOOD NEWS!”
“euaggelion” (from the Greek) means good news or glad tidings.

“You are the one who is ignoring the biblical definition.”
No. I allowed God to speak for Himself rather than interjecting my opinion. First Corinthians 15 tells us EXACTLY what the Gospel is. There are false gospels. See Galatians 1:6.
Not everything that someone might think is good news qualifies as the Gospel of the grace of God. Leaving out SIN from the Gospel as the Bible defines it, is a FALSE Gospel. I hope you understand the horrific ramifications of spreading a false gospel. See Galatians 1:8-9.
“Look up the verse where it says the holy spirit convinced people of sin, righteousness and judgement.”
John 16:7-8 NKJV
Nevertheless I tell you the truth. It is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I depart, I will send Him to you. And when He has come, He will convict the world of sin, and of righteousness, and of judgment.
When did the Helper come? Pentecost. After that, the Holy Spirit (the Comforter) began to “convict the world of sin, and of righteousness, and of judgment” through the people He filled. How does He convict? Using words spoken by Spirit-filled believers. I already illustrated this in my previous post.
Let’s look at what else Jesus said in the same conversation you mentioned:
John 15:20 NKJV
Remember the word that I said to you, “A servant is not greater than his master.” If they persecuted Me, they will also persecute you. If they kept My word, they will keep yours also.
When He said to remember He was referring to a broader teaching earlier:
Matthew 10:24-25a NKJV
A disciple is not above his teacher, nor a servant above his master. It is enough for a disciple that he be like his teacher, and a servant like his master.
We are supposed to follow Christ’s example. He is the model. Did He preach against sin? Yes, He did.
John 7:7 NKJV
The world cannot hate you, but it hates Me because I testify of it that its works are evil.
Jesus was hated for preaching against sin. In the above verse He is NOT speaking to His disciples but to His brothers who had not yet believed on Him. See verse 5. The reason the world did not hate his brothers is because they wanted to be people-pleasers. They did not do as Jesus did and speak out against sin.
God does not call us to be busybodies, going around trying to straighten everyone else out or pointing out every fault of everyone we meet. But we are supposed to speak the truth in love. And the truth includes that we are all sinners in need of a Savior.
Without preaching against sin, the Gospel would not make sense, and those who heard such an incomplete (or false) Gospel would not be able to understand or obey the commands of the Gospel, which are to repent and believe:
Mark 1:15b NKJV
Repent, and believe in the gospel.
