The physical body (one’s members/the flesh) is not made sinless the moment one receives God’s gift of salvation through Christ. The believer is still capable of sin. Sin is the result of the “old nature” and those sins come about by the actions of the flesh (the physical/mental/emotional state of the believer). Paul, in Romans 7 bewails this fact, “Who can deliver me from the body of this death?”
The one who accepts Christ as Savior is delivered from the penalty of sin (”There is, therefore, no condemnation to them that believe...”, from the power of sin (it can no longer render the believer [eternally] dead), but we are not delivered from the presence of sin (our full salvation) until the day we are “ever with the Lord” in eternity.
Christ, and Christ alone, is the only One ever referred to in Scripture as being “full of grace [and truth]” - John 1:14.
“...Christ is the only one ever referred to in scripture as being full of grace ...”
See the bible Luke 1:28 and inform both the Angel Gabriel and St. Luke of this since they don’t seem to have gotten the memo.
Not so. Acts 6:8 refers to Stephen as plErEs charitos, which literally means "full of grace" and just the same as the description used of Jesus in John 1:14.
