How do we know the security of our salvation is true?

The security of salvation is confirmed in the Scriptures, particularly in John 10, where Jesus states that His sheep hear His voice, and no one can pluck them from His hand. This emphasizes not only the protective care of Christ but also the eternal nature of salvation. Believers' lives are 'hid with Christ in God,' reflecting their secure position in Him. Furthermore, eternal life cannot be temporary; if it were, it wouldn’t be called eternal. This doctrine reassures believers that their salvation is not based on their performance or ability to maintain faith but on God's sovereign grace and promise of preservation.
