No - being a believer DOESN'T save you, as I educated you earlier in James 2:19, where he says that even the DEMONS are believers.
True Faith, as James points out = Belief + Works (obedience (James 2:14-26).
As for your second ignorant comment in RED - the answer is NO. Satan CANNOT do good works.
Good works are those done for GOD'S glory - and nobody else's. Even if you feed the hungry and clothe the naked - they are NOT good works if you are doing them for ANYTHING other than God's glory.
You should KNOW this . . .
Nice try at deflecting. (James 2:19) destroys your water baptism regeneration.
The infant has neither faith or works.
