Passage
and He who is confirming you with us into Christ, and did anoint us, <FI>is<Fi> God,
and He who is confirming you with us into Christ, and did anoint us, <FI>is<Fi> God,
2 Corinthians 1:19 for the Son of God, Jesus Christ, among you through us having been preached--through me and Silvanus and Timotheus--did not become Yes and No, but in him it hath become Yes;
2 Corinthians 1:20 for as many as <FI>are<Fi> promises of God, in him <FI>are<Fi> the Yes, and in him the Amen, for glory to God through us;
2 Corinthians 1:21 and He who is confirming you with us into Christ, and did anoint us, <FI>is<Fi> God,
2 Corinthians 1:22 who also sealed us, and gave the earnest of the Spirit in our hearts.
2 Corinthians 1:23 And I for a witness on God do call upon my soul, that sparing you, I came not yet to Corinth;
The verse centers on "confirming", "christ", and "anoint". It is saying that the verse draws attention to "confirming" and "christ", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 20's "for as many as FI are Fi..." into verse 22's "who also sealed us and gave the...", so "confirming" and "christ" belong inside that flow. In 2 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "confirming" and "christ" with trust shaped by these words, not by a vague optimism outside the passage.
