Charles Spurgeon Commentary 1 Corinthians 1:7-8

"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 1:7-8 (ASV)

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.

Paul continues to recognize the abundance of their endowments and to express for them the utmost affection. He then adds his full conviction that God would prove the power of his grace by keeping them until the end, and then presenting them blameless in the day of our Lord Jesus Christ.
