“Therefore do not pronounce judgment before the time, before the Lord comes, who will bring to light the things now hidden in darkness and will disclose the purposes of the heart” (v5). Paul and other leaders were being criticized by the Corinthians, compared with one another, and Paul warned them about the dangers of judging. We see outward things like skills or appearance, but the Lord sees “the purposes of the heart.” He knows us better than we know ourselves (v3-4).
“Then each one will receive his commendation from God” (v5). We live to please the Lord, not other people. His standards are higher, and He sees our hearts.
