The Gospel is the good tidings that God revealed to us in Christ Jesus.
All mankind was represented in Adam and in his fall all of us became the children of wrath sentenced to death and separation from God.
Jesus Christ, the second Adam, takes man’s nature upon Himself fulfilling every jot and tittle of the law and takes upon Himself the punishment and death due us. Since He was sinless death could not hold him and He was raised for our justification.
Now by command of the Father this mediation is preached to all men everywhere that upon repentance and belief in Him not only are all our sins forgiven but also we will spend ETERNITY with Him in heavenly bliss.
NOW THAT’S “GOOD NEWS”.
