Charles Spurgeon Commentary 1 Corinthians 1:5-8

"that in everything ye were enriched in him, in all utterance and all knowledge; even as the testimony of Christ was confirmed in you: so that ye come behind in no gift; waiting for the revelation of our Lord Jesus Christ; who shall also confirm you unto the end, [that ye be] unreproveable in the day of our Lord Jesus Christ." — 1 Corinthians 1:5-8 (ASV)

That in everything you are enriched by him, in all utterance, and in all knowledge; even as the testimony of Christ was confirmed in you: so that you come behind in no gift; waiting for the coming of our Lord Jesus Christ: who shall also confirm you unto the end, that you may be blameless in the day of our Lord Jesus Christ.

It was very wise of Paul thus to praise these Corinthians where they could be praised, for he was about to upbraid them and reprove them for many things which were not pleasing to God. If you have the unpleasant duty of rebuking those who deserve it, always take care that you begin by saying all that you can, and all that you ought, in their favor; it will prepare the way for what you have to say to them afterwards.

The Corinthians were a highly-gifted church; they probably had more knowledge and more of the gifts of utterance than any other church of their day; but, alas! they fell into greater sin than did their sister churches. Great gifts are not great graces; but great gifts require great graces to go with them, or else they become a temptation and a snare. Yet Paul felt quite sure that God would keep even these Corinthians with all their imperfections, and confirm them unto the end; and what was true of them, is also true of all the Lord's people, God will preserve them to the very end.
