1:4 I always thank my God for you because of the grace of God that was given to you in Christ Jesus. 1:5 For you were made rich 1 in every way in him, in all your speech and in every kind of knowledge 2 –
1 sn Made rich refers to how God richly blessed the Corinthians with an abundance of spiritual gifts (cf. v. 7).
2 sn Speech and knowledge refer to the spiritual gifts God had blessed them with (as v. 7 confirms). Paul will discuss certain abuses of their gifts in chapters 12-14, but he thanks God for their giftedness.
