Now a Jew named Apollos, a native of Alexandria, came to Ephesus. He was an eloquent man, competent in the Scriptures. He had been instructed in the way of the Lord. And being fervent in spirit, he spoke and taught accurately the things concerning Jesus, though he knew only the baptism of John. He began to speak boldly in the synagogue, but when Priscilla and Aquila heard him, they took him and explained to him the way of God more accurately. And when he wished to cross to Achaia, the brothers encouraged him and wrote to the disciples to welcome him. When he arrived, he greatly helped those who through grace had believed, for he powerfully refuted the Jews in public, showing by the Scriptures that the Christ was Jesus.
Priscilla and Aquila were tent makers. They were not seminary graduates or even students. They had been taught by Paul, but so had a great many other people. Yet God chose to use them to mentor a well educated, well spoken Alexandrian named Apollos. Apollos was a man whom Paul, later, counted as an equal in missionary service. What qualified Priscilla and Aquila for this calling? It was not training. It was not pedigree.
It was willingness.
Too often Christians expect their pastor to lead all the Bible studies, community groups, visitations, officiate all funerals and generally do all the ministry of the church. But according to scripture the purpose of the pastors is not to do all the ministry, but to train the members for ministry.
Priscilla and Aquila ministered. They didn’t write to Paul and tell him that he needed to come back and set Apollos straight. They took Apollos aside and explained as best they could what Paul had taught them.
I think the key here is the phrase, “As best they could.” God doesn’t expect us to be perfect, but to be willing. It’s okay, when leading a Bible study, or teaching a Sunday School class or talking to your neighbor to admit you don’t know. I recently heard a pastor say, “My people expect me to have an answer for everything and I do. It’s usually, ‘I don’t know’.” Just do the best you can. Give you best to God, and trust Him for the results.
The point is that every Christian is a minister of the Gospel.
