Entering through the narrow gate or The path of the least resistance...

The narrow gate is the "stripping away" gate. Because of that you might call it a path of much resistance.

No, I think they're different things, path of least resistance is a 'go with the flow' thing and 'narrow gate' is a 'do it tough' thing? or something like that.

thank you

it's the easy path if you're not torn between sides and have faith. he says "For my yoke is easy and my burden is light.”
