John 15:3

Misinterpretations often reduce this to physical or ritual cleanliness from Old Testament washings, ignoring its spiritual context; others claim automatic sinlessness upon hearing the word without faith or ongoing abiding, or twist it into a works-based salvation where human effort alone purifies, detached from Christ's redemptive role and the vine-branch metaphor.

Jesus declares his disciples clean through the purifying power of his spoken word, emphasizing that true spiritual cleansing comes from receiving and believing his teachings as the divine truth that transforms the heart, enabling believers to abide in him as fruitful branches in the vine, distinct from mere external purification.
