'One' in the Bible

We must always thank God for you, brothers. This is right, since your faith is flourishing and the love each one of you has for one another is increasing.

For the mystery of lawlessness is already at work, but the one now restraining will do so until he is out of the way,

and then the lawless one will be revealed. The Lord Jesus will destroy him with the breath of His mouth and will bring him to nothing with the brightness of His coming.

The coming of the lawless one is based on Satan’s working, with all kinds of false miracles, signs, and wonders,

But the Lord is faithful; He will strengthen and guard you from the evil one.
