Paul worked with his hands. The apostle to the Gentiles paid his own way much of the time, refusing to be a burden (1 Thessalonians 2:9). Christian ministry has no necessary connection to financial dependence.

A bivocational pattern modeled by the chief missionary. Where the work allows, working a trade alongside ministry preserves freedom from accusation and provides for those in need. Paul boasted of it as part of his integrity.

Much people in this city. The Lord has elect in Corinth not yet gathered. The unconverted Corinthians whose names Paul did not know were already on God's list. Evangelism is gathering what is already chosen.

I am with thee. The deepest courage in ministry. The Lord's presence is not an abstraction; it is the assurance that quiets the apostle's fear. Paul stayed eighteen months — long, because the Lord had said much was there.

Apollos is a gift to the church — eloquent, gifted, biblically saturated. But his theology was incomplete (v.25 — knew only John's baptism). Aquila and Priscilla, the tentmaking couple, take him aside and expound unto him the way of God more perfectly (v.26).

A gifted preacher is teachable. He listens to a husband-and-wife layperson team and grows. Pride would have refused; humility flourished. The greatest growers are the ones not too important to be taught.

The pattern of private correction. They did not stand up in the synagogue to embarrass him; they took him aside. Where correction is needed for a public teacher, the back room is the first venue, not the platform.

Aquila and Priscilla — a couple in ministry together — make a quiet but immense contribution. They host churches in their home (1 Corinthians 16:19), travel with Paul, mentor the next great preacher. Quiet faithful couples shape generations.
