Where is the Gospel explained in the Bible?
What is this Gospel?
Gospel, a word used only 77 times in the Bible and only in the New Testament, is a word that very few english speaking people in the world are not familiar with, or at least have heard throughout their lives. In the minds of many it is a word used often to mean that something is true, and it is just that. Just what does the word Gospel actually mean? According  to Strong’s Greek Concordance it means simply, “a good message”. Many preachers and church going people say that it means “Good News”, and indeed it is exactly that. 
According to God’s Word, just what is this Good News, this good message, that this Gospel the Bible refers to? Where can the true definition of the Gospel be found in the Bible? Here is the explanation of the Gospel given by a man inspired by God’s Holy Spirit. This explanation of the Gospel is given by Paul, described by some christians as the greatest preacher in all of history.

Here is the explanation of the Gospel given by Paul in the Bible:
1 Cor. 15:1-11 (NKJV)
1 Moreover, brethren, I declare to you the gospel which I preached to you, which also you received and in which you stand,
2 by which also you are saved, if you hold fast that word which I preached to you—unless you believed in vain.
3 For I delivered to you first of all that which I also received: 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, (emphasis mine)
5 and that He was seen by Cephas, then by the twelve.
6 After that He was seen by over five hundred brethren at once, of whom the greater part remain to the present, but some have fallen asleep.
7 After that He was seen by James, then by all the apostles.
8 Then last of all He was seen by me also, as by one born out of due time.
9 For I am the least of the apostles, who am not worthy to be called an apostle, because I persecuted the church of God.
10 But by the grace of God I am what I am, and His grace toward me was not in vain; but I labored more abundantly than they all, yet not I, but the grace of God which was with me.
11 Therefore, whether it was I or they, so we preach and so you believed.
