Anyone who has been of this Forum in the past few days has seen Doubting Thomas (an active JW) refuse over and over to provide even one scripture that can show how a JW can get their sins forgiven while outside of the New Covenant as described in Mt. 26: 27-28. Yet, he claims to believe in the blood covering of Jesus while at the same time personally rejecting the new covenant "for forgiveness of sins". His contradictory claims are common among JW's.
And taking a cup, he offered thanks and gave it to them, saying: “Drink out of it, all of you, for this means my blood of the covenant, which is to be poured out in behalf of many for forgiveness of sins". - NWT

"The ...other sheep..are...not even justified." WT 1938 pages 104-105
Websters Dictionary defines Justification as : remission of sin and absolution from guilt and punishment; or an act of free grace by which God pardons the sinner and accepts him as righteous, on account of the atonement of Christ.
This is still official WT dogma. - Just a FYI
The good news is that the Atonement is still open for business... if you are a "whosoever".
- But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life.
And when he had called the people unto him with his disciples also, he said unto them, Whosoever will come after me, let him deny himself, and take up his cross, and follow me.
