What does 1 Corinthians 16:12 mean?
One of the issues dividing the Corinthian church was a completely unnecessary conflict over which apostle or teacher the people should be loyal to (1 Corinthians 1:10–12). Paul rejected this as foolish and made it clear that he did not consider other Christian leaders, including Apollos, to be competition, but instead "God's fellow workers" (1 Corinthians 3:9).In fact, Apollos had been working with Paul in Ephesus. When Paul decided to send Timothy and others to Corinth, he writes now that he "strongly urged" Apollos to go, as well. This should demonstrate to the Corinthians once more that Paul does not see himself in competition with Apollos and, in fact, would see great value in Apollos spending more time with the Corinthians.
Apollos, though, chose not to go. Language experts disagree whether the text should read that it was God's will for Apollos not to go or if Apollos himself simply did not want to. Some suggest that perhaps Apollos did not want to add to the divisions among the Corinthians by spending time with them again, but that is speculation.
Paul adds that Apollos will come when he has the opportunity.
