If he accepted Jesus Christ as his Lord and Savior then he will go before the Bema Seat of Christ.
Yes, if he received the Lord Jesus Christ as his Savior from sin, he has been justified by faith in Christ (declared righteous by God), and is forgiven of all his sins—past, present, and future—but his works will be judged (1 Corinthians 3:13-15)before the judgment seat (bema) of Christ.
From what I could find out about Mr. Tremmel, “he never broke his silence about what he did in the SS” (post #95);
I would think that true repentance could not remain silent.
