Jn 13:10
Jesus said to him, “The one who has bathed [saved] does not need to wash, except for his feet [ref: let the word wash the daily filth off of you - aka, let it sanctify you - ala Jn 17:17], but is completely clean. And you are clean, but not every one of you [Judas was unsaved].”

1Pe 1:22 - Positional & Experiential Sanctification
“Having purified your souls” (ref. positional sanctification), believers are obliged to “love one another earnestly from a pure heart [the new heart we are given at salvation]” (ref. Experiential sanctification).
