Christ Qua ἱλάσμος For "Our Sins" (1 John 2:1-2)

In 1 John 2:1-2, the apostle professes that Christ is ἱλάσμος for "our sins," but not for "ours" alone. To demonstrate the referent of the pronoun "our," I believe some good verses to adduce would be the following:

"But you have been anointed by the Holy One, and you all have knowledge" (1 John 2:20 ESV).

"As for you, the anointing which you received from him remains in you, and you don't need for anyone to teach you. But as his anointing teaches you concerning all things, and is true, and is no lie, and even as it taught you, you will remain in him" (1 John 2:27 WEB).

"beloved, now, children of God are we, and it was not yet manifested what we shall be, and we have known that if he may be manifested, like him we shall be, because we shall see him as he is" (1 John 3:2 YLT)

1 John 3:2 is a complex scripture, but it seems that the most likely explanation of the passage is that it references the Father, whom anointed Christians will one day "beatifically" see.
