When I look in the mirror, I see a sinner in need of Lord Jesus Christ, the Risen Son of Almighty God, King of Kings and Lord of Lords.
I don't know how anyone looks in the mirror and sees Christ, unless they are deluded.
The "mirror" allusion was regarding our good works or our condemnation, remember? It is just plain sad that Roman Catholics believe their good works are their own when they are actually Jesus Christ within them and they in Him.
"To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory" -- Colossians 1:27
"But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me." -- 1 Corinthians 15:10 "That the communication of thy faith may become effectual by the acknowledging of every good thing which is in you in Christ Jesus." -- Philemon 1:6
If you do not perceive Christ in you, you should return to your Bible and look for Him.
