The Gospel
1st Corinthians 15:3-4 (KJV)
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4 And that he was buried, and that he rose again the third day according to the scriptures:
THE APOSTLE PAUL SAYS MANY HEAR THE GOSPEL AND DON'T UNDERSTAND IT
ACTS 28:26-28
26 Saying, Go unto this people, and say, Hearing ye shall hear, and shall not understand; and seeing ye shall see, and not perceive:
27 For the heart of this people is waxed gross, and their ears are dull of hearing, and their eyes have they closed; lest they should see with their eyes, and hear with their ears, and understand with their heart, and should be converted, and I should heal them.
28 Be it known therefore unto you, that the salvation of God is sent unto the Gentiles, and that they will hear it.
