For though I preach the gospel, I have nothing to glory of: for necessity is laid upon me; yea, woe is unto me, if I preach not the gospel! — 1 Corinthians 9:16
The Apostle Paul felt compelled to preach the gospel. When we become believers, the Holy Spirit plants within us the desire to share the gospel! So what is it that we are to preach? Well, what did Paul preach as the gospel?
1 Corinthians 15 sums up Paul's preaching of the gospel.
15:1 Now I want to make clear for you, brothers and sisters, the gospel that I preached to you, that you received and on which you stand, 15:2 and by which you are being saved, if you hold firmly to the message I preached to you – unless you believed in vain. 15:3 For I passed on to you as of first importance what I also received – that Christ died for our sins according to the scriptures, 15:4 and that he was buried, and that he was raised on the third day according to the scriptures, 15:5 and that he appeared to Cephas, then to the twelve. 15:6 Then he appeared to more than five hundred of the brothers and sisters at one time, most of whom are still alive, though some have fallen asleep. 15:7 Then he appeared to James, then to all the apostles.
Paul's four elements of the gospel message (the core of Christianity):
1. Christ died for our sins.
2. He was buried.
3. He was raised on the third day.
4. He appeared to many.
Christ's death and resurrection are at the heart of the gospel. The fact that He was buried verified His death, and the fact that He appeared to others verified His resurrection.
Charles Haddon Spurgeon once preached a sermon titled "What is it to Preach the Gospel?" In that sermon he stated that:
"To Preach the Gospel is...
To Tell The Truth About God
To Tell The Truth About Man
To Tell The Truth About Christ
To Tell The Truth About Salvation"
