How do we know Christ did not die for everybody?

The sermon articulates that the understanding of Christ’s death being limited to the elect is affirmed through multiple Scripture references. For instance, John 10:14-15 states, 'I am the good shepherd and know my sheep, and am known of mine.' This indicates a personal relationship and specific intent in His sacrificial death. Jesus did not attempt to save everyone but accomplished the salvation of those given to Him by the Father, confirming that He did not die in vain for souls that would ultimately not be saved.
