1 Korintus 1:5-6

1:5 For you were made rich ¹  in every way in him, in all your speech and in every kind of knowledge ²  – 1:6 just as the testimony about Christ has been confirmed among you –

[1:5]  ¹ sn Made rich refers to how God richly blessed the Corinthians with an abundance of spiritual gifts (cf. v. 7).

[1:5]  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.
