But when Priscilla and Aquila heard him, they took him aside and explained the way of God more accurately to him.

​“Now a Jew named Apollos, an Alexandrian by birth, an eloquent man, came to Ephesus; and he was proficient in the Scriptures. This man had been instructed in the way of the Lord; and being fervent in spirit, he was accurately speaking and teaching things about Jesus, being acquainted only with the baptism of John; and he began speaking boldly in the synagogue. But when Priscilla and Aquila heard him, they took him aside and explained the way of God more accurately to him.”

We have this new traveling minister show up in Ephesus named Apollos. He was preaching Jesus from the viewpoint of John’s baptism. But Pricilla and Aquila saw that he was lacking something in his walk with Christ and that was the baptism of Jesus with fire from the Holy Spirit. I like to point out that Pricilla and Aquila took him aside to their home and better explained Jesus to Him. He began to preach Jesus with more vigor refuting those who would challenge him (vs28). 

“For when one person says, “I am with Paul,” and another, “I am with Apollos,” are you not ordinary people? What then is Apollos? And what is Paul? Servants through whom you believed, even as the Lord gave opportunity to each one. I planted, Apollos watered, but God was causing the growth. So then neither the one who plants nor the one who waters is anything, but God who causes the growth. 

So then, no one is to be boasting in people. For all things belong to you, whether Paul or Apollos or Cephas, or the world or life or death, or things present or things to come; all things belong to you, and you belong to Christ, and Christ belongs to God.”

Later in the writings of Paul to the Corinthian church Apollos shows up again. This time he is used as a separation in the church. The church was splitting into possibly three groups of disciples; Paul, Apollos, and Cephas (Peter). But Paul had only one disciple maker, God, who causes growth. 

We do not belong to the church of Paul, Apollos, or Peter, but the church of God through the blood of Jesus has redeemed us back into fellowship with God. And by the power of the Holy Spirit, we can be witnesses for Him. 

Apollos would never have been able to refute the Jews without the disciple-making ability of Pricilla and Aquila who learned it from Paul. Who learned it from Barnabas. Who somewhere learned it from Jesus. And today we will not be able to learn disciple-making until we first learn how to be a disciple by submitting to another’s leadership. So that we learn how to follow them as they point their lives to Jesus. 

“Be imitators of me, just as I also am of Christ.”
