What does it mean that believers have heard God's voice?

When the preacher refers to believers having heard God's voice, he emphasizes the transformative power of God's call in their lives. It signifies that God, in His grace, opens the ears and hearts of those He elects to respond to His truth. This hearing is not merely physical but spiritual, signifying new life in Christ. The sermon connects this hearing to the promise that believers will live eternally with Christ, illustrating that hearing God's voice is linked to faith and salvation, as seen in passages like John 5:25, where Jesus asserts that the dead shall hear His voice and live.
