One knows they are part of the elect by having faith in Christ and experiencing a transformed life through the Holy Spirit.
Assurance of being part of the elect comes through faith in Christ and the evidence of transformation in one's life. Jesus indicates in John 10:27 that His sheep hear His voice, and He knows them; they follow Him. This relationship reflects an active faith and obedience to His calling. Moreover, the presence of the Holy Spirit works within believers, producing fruit that confirms their identity in Christ. Romans 8:16 affirms that the Spirit Himself bears witness with our spirit that we are children of God. Thus, the assurance of election is tied to a genuine relationship with Jesus and the work of the Holy Spirit in the believer's life, fostering belief and obedience.
