I've read and listened to where Ray showed that 1 Cor 3:15 is a match for the lake of fire in Revelation and showing that everyone's work will be judged by fire but the man himself will be saved.
1 Cor 3:10-15
10 By the grace God has given me, I laid a foundation as a wise builder, and someone else is building on it. But each one should build with care. 11 For no one can lay any foundation other than the one already laid, which is Jesus Christ. 12 If anyone builds on this foundation using gold, silver, costly stones, wood, hay or straw, 13 their work will be shown for what it is, because the Day will bring it to light. It will be revealed with fire, and the fire will test the quality of each person’s work. 14 If what has been built survives, the builder will receive a reward. 15 If it is burned up, the builder will suffer loss but yet will be saved—even though only as one escaping through the flames.
My question is, doesn't this sound like Paul is talking about believers only? Isn't he talking about only people who've built their spiritual house upon the foundation of Jesus?
