The Gospel is Christ Centered.
Mark starts off writing in Gospel according to Mark, that it is the beginning of the gospel of Jesus Christ (Mark 1:1).
Paul in his letter to Thessalonians tells them about the Judgement at Christ’s coming by telling them the truth of who do not obey the gospel of Lord Jesus. (2 Thessalonians 18) and many other places in the Bible specifically mentions about to whom the Gospel belongs to ( Romans 15:19, 1 Cor 9:12, 2 Cor 2:12, 2 Cor 9:13, 2 Cor 10:14, Galatians 1:7, etc) In all the places where they teach, preach, exhort, warn it exalts Lord Jesus Christ. He is the center of all of this. It is certainly not HumanCentric. Martin Luther summarized it best: “Gospel is and should be nothing else than a discourse or story about Christ.”
The Gospel is Cross-Centered.
There is no gospel without shedding of blood, there is no gospel without a sacrifice, there is no gospel without the payment. There is no gospel without the exchange. There is no gospel without the cross.
Gospel is and should be nothing else than a discourse or story about Christ
Later in the same letter, Paul adds this: And I, when I came to you, brothers, did not come proclaiming to you the testimony of God with lofty speech or wisdom. For I decided to know nothing among you except Jesus Christ and him crucified. (1 Cor. 2:1–2)

The Gospel is Grace Centered.
Scriptures repeatedly talk about to whom gospel belongs and its nature (goodness). One of the reason it’s necessarily good because it’s free and it doesn’t depend on us. Therefore, the Gospel is Grace Centered.
Because the gospel is something outside us, it’s necessarily grace-centered. The work of the gospel is applied to those who believe—not because of anything in them, but in spite of the fact that there’s nothing anyone can do to deserve it. The gospel is good news precisely because it is grace-centered.
What a glorious privilege it is to “testify to the gospel of the grace of God” (Acts 20:24)!
