Jn 3:16-----------believing>>>>>>>>>>>>saves
Lk 13:3,5---------repenting>>>>>>>>>>>>saves/not perish
Mt 10:32,33------confession>>>>>>>>>>>saves
Mk 16:16---------baptism>>>>>>>>>>>>saves
Since there is just one way to be saved, no alternatives, then belief must include repentance, confession and baptism. Therefore when the bible says "whosoever believeth in him should not perish, but have everlasting life" some people assume the verse says "believeth only" instead of correctly understanding that 'believeth" in this verse includes repentance, confession and baptism. Jesus would not/did not contradict Himself by saying one one hand "belief only" saves but then say one the other hand repentance confession and baptism also save.
A Christian's faith includes the good works Christian are required to do, Eph 2:10; Matt 25:31-46. No text gives a specific number of good works a Christian is to do each day but the Christian is to do good works as the opportunity presents itself, Gal 6:10.
How many "Christians" make it into heaven with zero good works? Zero.
