In this message, Pastor Leger emphasizes the importance of having a teachable spirit by using the story of Apollos from Acts 18:24-28. He illustrates how Apollos, despite his enthusiasm for God, had an incomplete understanding of the gospel, highlighting the need for continuous spiritual growth and deeper knowledge of God's Word. Pastor Leger encourages us to be humble and open to learning from others, as well as to seek out relationships that foster spiritual development.
