How can we be sure we are among the elect?

Assurance of being among the elect stems from faith in Christ, as outlined in John 6:40 where it states that whoever sees the Son and believes in Him will have everlasting life. The ship in Acts 27 symbolizes Christ; those aboard are secured by their connection to Him. To know if one is in the 'ship,' consider whether you see Christ as the true Son of God and trust in Him alone for salvation. It is not about one's perceived strength of faith but the sufficiency of the Savior. Thus, confidence in one’s election arises from an understanding of and belief in Jesus Christ, and His unwavering promise of salvation.
