When we repent, we change our mind about our sinful position and need for Christ to save us and the new direction of this change of mind is faith in Christ alone for salvation. Two sides to the same coin. (Acts 20:21)
Those who have repented will demonstrate their repentance by their deeds (Acts 26:20) and will no longer practice sin, but practice righteousness. (1 John 3:9-10)
It sounds to me like YTG defines "repent" as "completely stop sinning/become sinless" and obtaining salvation then becomes based on the merits of our performance in becoming sinless, yet believers are not sinless, without fault or defect, flawless, 100% of the time.
What you are expressing has been the main-line traditional belief system.
It is a walk of sanctification to end up walking like Jesus.
The tension has always been seeing our transformation fully fulfilled in Christ and our walk.
And the barrier is how closed our hearts are, and are we willing to change.
Because we have no compromise with sin, it is hard to specify how for each individual this
is worked out as we have many weaknesses and much to grow into.
This view of transformation very different from an evil flesh fighting a perfect spirit.
It is this flipping of the discussion as if we are talking a traditional framework to one
that is not Christian, when the very people discussing this hold to the perfect spirit,
lost flesh model.
But then being honest about their own beliefs has never been the way some discuss.
It must be because that view is simply not supported in scripture. Just as the defeated
believer in sin, is simply not saved.
