1 Corinthians 15:15-20 Yea, and we are found false witnesses of God; because we have testified of God that he raised up Christ: whom he raised not up, if so be that the dead rise not. 16 For if the dead rise not, then is not Christ raised: 17 And if Christ be not raised, your faith is vain; ye are yet in your sins. 18 Then they also which are fallen asleep in Christ are perished. 19 If in this life only we have hope in Christ, we are of all men most miserable. 20 But now is Christ risen from the dead, and become the firstfruits of them that slept.
The early church was often ridiculed for believing that Christ literally rose from the dead. Paul explains here that if Christ didn't rise from the dead there is no resurrection for the rest of us either. In fact, if Christ has not risen, our faith is empty and we are still in bondage to our sins.
Just imagine if Christ had not risen from the dead. Christianity would be no different than any other religion. Every other religion has a human figure behind it and they are all in the grave. Even Muhammed the "great" prophet died and is buried to this day. That's where Christianity is unique. The Lord Jesus is our human figure, but although his life is historically documented, his bones are nowhere to be found.
1 Corinthians 15:3-8 says... 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: 5 And that he was seen of Cephas, then of the twelve: 6 After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep. 7 After that, he was seen of James; then of all the apostles. 8 And last of all he was seen of me also, as of one born out of due time.
He is alive and because He lives, we can look forward to everlasting life in heaven with Him
