Acts 18
24 Now a certain Jew named Apollos, born at Alexandria, an eloquent man and mighty in the Scriptures, came to Ephesus. 25 This man had been instructed in the way of the Lord; and being fervent in spirit, he spoke and taught accurately the things of the Lord, though he knew only the baptism of John. 26 So he began to speak boldly in the synagogue. When Aquila and Priscilla heard him, they took him aside and explained to him the way of God more accurately. 27 And when he desired to cross to Achaia, the brethren wrote, exhorting the disciples to receive him; and when he arrived, he greatly helped those who had believed through grace; 28 for he vigorously refuted the Jews publicly, showing from the Scriptures that Jesus is the Christ.

Be willing to learn.
Apollos was a mighty man of the scriptures. However, what Apollos knew was old information.
Aquila and Priscilla updated Apollos on more recent events, like Jesus Christ crucified.

However, Apollos could have rejected their teachings and assumed he was right. Apollos could have been stubborn and ignored them since he himself was “mighty in the Scriptures,” but he didn’t.

We must be willing to grow and learn as Christians. Let us never pretend that we know everything. We can learn from anyone at anytime. The Holy Spirit will guide us in truth.
