What will people who survive all seven years of the Tribulation see?
Those who endure to the end of the seven-year Tribulation will see the light at the end of the tunnel. This endurance refers not to salvation but to physical survival through that whole period. They will come through the entire seven years and see the light at the end of the tunnel.
Les explains that the verse “he that shall endure unto the end, the same shall be saved” is often twisted, lifted out of context, and mistaught. In this setting it is not about salvation but about physical survival. He points to Isaiah 24, where the Lord makes the earth empty, waste, and turns it upside down during the Tribulation. Those fortunate enough to come through the whole seven years will see the light at the end of the tunnel.
