It is this Good News that saves you if you continue to believe the message I told you—unless, of course, you believed something that was never true in the first place.
I passed on to you what was most important and what had also been passed on to me. Christ died for our sins, just as the Scriptures said. He was buried, and he was raised from the dead on the third day, just as the Scriptures said. He was seen by Peter and then by the Twelve. After that, he was seen by more than 500 of his followers at one time, most of whom are still alive, though some have died. Then he was seen by James and later by all the apostles. Last of all, as though I had been born at the wrong time, I also saw him. For I am the least of all the apostles. In fact, I’m not even worthy to be called an apostle after the way I persecuted God’s church.
–1 Corinthians 15:2-9 NLT
We must continue to believe the message to be saved. What does this scripture do to the concept of “once saved, always saved“?
Part of the testimony that we have as a Christian is we acknowledge Jesus has risen from the dead. A person who believes Jesus rose from the dead is a Christian, anyone else is not. People saw Jesus and so will you who believe.
