Salvation is by faith (Jn 3:16  10:43; 16:31), but not by faith only  (James 2:24). “The demons believe,  and tremble” (Jas 2:19); “Many  believed… but did not confess him”  (Jn 12:42). Salvation is by repentance  (Ac 11:18), but not by this alone:  “If you do not believe (in Jesus) you  will die in your sins”
