1 Cor 1:4-6 (NIV) I always thank God for you because of his grace given you in Christ Jesus. 5 For in him you have been enriched in every way — in all your speaking and in all your knowledge— 6 because our testimony about Christ was confirmed in you.
NOTE: I'm not sure what comes first. Are the Corinthians enriched because of Paul's testimony? Or is Paul's ministry confirmed because of their enrichment from God? Either way, real life in Christ should show some difference. I look at my navigator friends from college, and I see so many serving God in very different and unique ways. Their work of faith confirms the testimony of those who shared Christ with them. No wonder Paul starts out by saying, "I always thank God for you because of his grace given you in Christ Jesus." I feel the same way, so unworthy of the people I helped come to Christ or even to grow in their relationship with the Savior. Why am I? Nobody, but I hope someone that is useful to my savior.
