1 Corinthians 15:2 Commentary and Bible Study

Paul does not mean that they must believe in order to stay saved. No, if you are saved, you will continue believing. If you fail to believe, it is because you ‘have believed in vain’. You never really put your trust in Christ. You never came to him and repented of your sin. There was no true work of grace in your heart, and you ‘have believed in vain’, because it was a shallow kind of belief. It wasn’t with your heart. You never had the evidence of true conversion. In that case, we must come to Christ for the first time and repent before him with all sincerity, and trust in his shed blood.
