This is terrifying. It will be better for Sodom on that day. I’m not even sure what I mean by that.
Believers who are saved today possess the spirit of Christ, and the Father, and produce fruits of the spirit appropriate for the Kingdom in the present time.
However, not all actions are carried out in Christ by believers, nor do they remain in Him constantly; some are done with selfish intentions in mind and heart, failing to fulfill God's will. A believer is already aware of these actions in their life and understands that they will not be rewarded for them. These works are effectively "burned up" as soon as they are conceived and carried out, never to have significance in the Kingdom life of a saved person today.
1 Corinthians 3:15 teaches that believers can experience the burning of their works now, rather than waiting for a future day of judgment. The "fire" mentioned in this passage is often understood as divine judgment, refinement, or God's examination during a believer's earthly life.
Testing of Works: The passage uses the metaphor of building materials (gold, silver, wood, hay) to symbolize the quality of a believer's service.
Present Burning: Some interpretations suggest that when believers serve with motives or methods that do not align with the Gospel (such as "wood, hay, and straw"), those works are "burned" or made worthless immediately by God’s refining fire.
Loss of Reward: Although the believer is saved, the loss of these worthless works is experienced either immediately or gradually throughout the Christian journey, resulting in that type of life without eternal significance.
Saved as Through Fire: The phrase "saved, but only as through fire" indicates a narrow escape, where the individual is preserved but has failed to build only a few things or nearly nothing enduring for the Kingdom during their lifetime. This applies to nearly all believers who ever lived and those pf today or tomorrow.
Therefore, the burning of works is not a future event but is truly present reality during their life today, where God exposes and removes the temporary elements of a believer's service. And in the next life, believers, knowing some of their fruits are false, already know and expect this outcome and will not be surprised. They wished they had abided consistently in Christ as their true earthly lifestyle, in their Kingdom life, and not living as a hobby life of service for God.
And as for the comparison of Sodom on that Day,..it is a warning for non-believers. Believers possess Christ already.
The statement emphasizes that greater privilege entails greater responsibility. Since Sodom was destroyed for its sins without having witnessed the Messiah’s direct ministry, its judgment is considered less severe than that of the towns like Capernaum, which had direct access to Yeshua's teachings and miracles but chose to reject them, and thus remained unbelievers.
I hope this helps clarify a few things for you.
