How do believers know they are part of the elect?

The election of believers is grounded in the sovereign grace of God, which is evident in their response to the Gospel message. In John 10:27, Jesus says, 'My sheep hear my voice, and I know them, and they follow me.' This indicates that the true elect are characterized by their faith and obedience to Christ. Additionally, 2 Thessalonians 2:13 assures us that God has chosen believers for salvation through sanctification by the Spirit and belief in the truth. Thus, a believer's assurance is found not in their own works but in their trust in Christ as the means of their election.
