Charles Ellicott Commentary 1 Corinthians 4:5

"Wherefore judge nothing before the time, until the Lord come, who will both bring to light the hidden things of darkness, and make manifest the counsels of the hearts; and then shall each man have his praise from God." — 1 Corinthians 4:5 (ASV)

Before the time.—This is explained by the following words to be “the day of the Lord.” When this arrives, the truth will be ascertainable, for God will bring into light all the things currently hidden in the darkness, and will make manifest the inner motives of each heart. Then every man (and not only one party leader, as at Corinth) will have his due and proper praise from God—not from man.
