What does rejecting Christ mean for salvation?

The peril of rejecting Christ is starkly highlighted in the sermon, where it is stated that there remains no more sacrifice for sins outside of Him. Those who willfully turn away from the knowledge of the truth are warned that they leave the only means of salvation and are in essence choosing to remain in their sins. As outlined in Hebrews 10, rejecting Christ is effectively rejecting all that God has provided for sinners. His sacrifice is the only one that can atone for sin, and to seek salvation elsewhere is a grave mistake that leads to eternal separation from God.
