1 Cor 4:5 refers to God, not Jesus. I am working with you here.
The "Lord" in 1 Corinthians 4:5 refers to Jesus.
1 Corinthians 4:5
Therefore judge nothing before the time, until the Lord comes, who both will bring to light the hidden things of darkness, and will disclose the motives of the hearts: and then shall every man have praise from God.
Try comparing what is in boldface above with 1 Corinthians 11:26 to see who the "Lord" is that Paul is referring to.
