What is this gospel sef??

Okay so last week I was reading the book of Romans 1 and in verse 16 the holy spirit explained some things to me most of us would neglect.
                   Rm. 1:16 " for I am not ashamed of the gospel of Christ for it is the power of God to salvation for everyone who believes, for the Jews first and also for the Greek"
 
      Now some Christians say they are preaching the gospel but what is the gospel? Firstly gospel means good news. Now that we know that,we know that anything that is not "good news" is not the gospel.let me explain that, the gospel (GOOD NEWS) of Christ is what attracts unbelievers because it is the "POWER" of God to salvation.so once unbelievers believe they are saved.you wonder why just saying some things the pastor tells you to say makes you a Christian? It's because when you hear this gospel, it convicts you due to its power ,then when you believe this "good news" in your heart you are saved because this "good news" is the power ( NOTE - not "has" the power, but "is" the power" )to make you saved once you believe.Therefore "BELIEVING" IS THE KEY THAT UNLOCKS THE POWER OF GOD UNTO SALVATION WHICH IS THE GOOD NEWS - THE GOSPEL OF CHRIST!!!
 God bless.
