Here's a short version of what he wrote to believers residing at Corinth.
He states that the risen Christ appeared (walked with, talked with) to:
- the twelve disciples
- more than 500 brethren at one time (some who were still alive when Paul wrote this chapter and quite able and willing to testify of the same)
- all the apostles
- to Paul himself
- there is no resurrection from the dead for us...when we die, we die. The End.
- it is pointless to preach Christ
- our faith in Christ is pointless
- what we proclaim as "truth" is mere "lie"
- those who have died have perished...there is no heaven
- Christ...the first to rise from the dead.
- In Adam (as descendants of Adam) we all die. None of us gets out of here alive.
- In Christ (joined to him by faith) we will be made alive.
- We get our resurrected bodies at his second advent (his second coming)
You can read Paul's more plainly here. I Corinthians 15:3-28
And Paul's concluding thoughts here. I Cor. 15:54-55
Jesus came to undo the work of the devil. He came to undo the death that Adam's sin brought to all of us. He came to put an end to death. An end to death? How can there be better news than that? And, hey! That thing about Jesus undoing the work of the devil? You can hover your cursor over the following verses to read about that.
1 John 3:8
On Easter we celebrate Christ's victory over death on our behalf. In Adam we die. In Christ we live. The latter only because Christ Himself lives and has conquered death.
J.C. Ryle (a much better writer than I) put it this way....We need not wonder that so much importance is attached to our Lord’s resurrection. It is the seal and memorial stone of the great work of redemption, which He came to do. It is the crowning proof that He has paid the debt He undertook to pay on our behalf, won the battle He fought to deliver us from hell, and is accepted as our guarantee and our substitute by our Father in heaven. Had He never come forth from the prison of the grave, how could we ever have been sure that our ransom had been fully paid (1 Corinthians 15:17)? Had He never risen from His conflict with the last enemy, how could we have felt confident that He has overcome death – and him that had the power of death, that is the devil (Hebrews 2:14)? But thanks be unto God, we are not left in doubt. The Lord Jesus really rose again for our justification.
And so we live by faith.
