‘If I knew I were one of God’s elect, I would come to Christ; but I fear I am not.’ To you I answer: nobody ever came to Christ because he knew himself to be one of the elect. It is quite true that God has of His mere good pleasure elected some to everlasting life, but they never knew it until they believed in Christ. Christ nowhere commands the elect to come to him. He commands all men everywhere to repent and believe the gospel. The question for you is not, ‘Am I one of the elect?’ but ‘Am I a sinner?’ Christ came to save sinners.
