“The beginning of the gospel of Jesus Christ, the Son of God;”
Mark 1:1 KJV
For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth. For therein is the righteousness of God revealed from faith to faith: as it is written, ‘The just shall live by faith.’ So continue in the faith grounded and settled, and be not moved away from the hope of the gospel, which ye have heard.
… Jesus went about all Galilee, teaching in their synagogues, and preaching the gospel of the kingdom, and healing all manner of sickness and all manner of disease among the people.

… the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed.

… he that shall endure unto the end, the same shall be saved.
And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
