WHAT GOSPEL IS THAT WHICH PETER, THE APOSTLE, TAUGHT AND PROCLAIMED?

“BECAUSE THERE ARE MANY GOSPELS, BUT A GOSPEL MEANS: "GOOD NEWS." THERE CAN BE MUCH GOOD NEWS. FOR EXAMPLE, A GOOD FRIEND, GETTING OF A LOVING FAMILY, COMING FROM FAR AWAY, TO SEE YOU, OF RECEIVING SOME PRECIOUS NEWS FROM SOMEONE. HOWEVER, YESHUA OUR SAVIOUR, CAME WITH A PARTICULAR GOOD NEWS. MY POINT IS, YESHUA WAS QUITE CLEAR OF WHAT HIS GOOD NEWS WAS. HIS GOOD NEWS WAS THE GOOD NEWS OF THE KINGDOM OF HEAVEN OR THE KINGDOM OF GOD. 1 PETER 4:17. WATCH OUT FOR THE SCRIBES, PHARISEES, AND SADDUCEES, WHO TAKE OUT AND ADD TO THE WRITINGS OF THE SCRIPTURES, AND ALSO THOSE WITH THE "LYING PEN", ACCORDING TO JEREMIAH 8:8.” (TNDL)
