Buddhism, more specifically vajrayana.

I think it’s better understood amongst practitioners that if you don’t walk the path then you’re not really a Buddhist.  I know this is true of pretty much all religions but there’s no, what I call, John 3:16 clause.  There are many Christian’s who think just believing in Jesus.  This may be true in other religions too but I’m from Christianity.  Buddhism gave me a different perspective on what it means to believe though.  To believe in a teacher is to follow and apply those teachings through every aspect existence.  Believe or take refuge in the teaching, not the vehicle that delivered that teaching.
