what is the Gospel?

• the Gospel can be found in 1 Corinthians 15:1-4
  • ❝Now, brothers and sisters, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand. By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain. For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures❞
  • believing in vain means believing with your mind but not your whole heart. There's also vanity which focuses more on what we do to "earn heaven", not Christ's finished work on the cross.
