Passage
(according as the testimony of the Christ has been confirmed in you,)
(according as the testimony of the Christ has been confirmed in you,)
1 Corinthians 1:4 I thank my God always about you, in respect of the grace of God given to you in Christ Jesus;
1 Corinthians 1:5 that in everything ye have been enriched in him, in all word [of doctrine], and all knowledge,
1 Corinthians 1:6 (according as the testimony of the Christ has been confirmed in you,)
1 Corinthians 1:7 so that ye come short in no gift, awaiting the revelation of our Lord Jesus Christ;
1 Corinthians 1:8 who shall also confirm you to [the] end, unimpeachable in the day of our Lord Jesus Christ.
The verse centers on "testimony", "christ", "been", and "confirmed". It is saying that the verse draws attention to "testimony" and "christ", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "that in everything ye have been enriched..." into verse 7's "so that ye come short in no...", so "testimony" and "christ" belong inside that flow. In 1 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "testimony" and "christ" with trust shaped by these words, not by a vague optimism outside the passage.
