Acts 18:25-26

25This man had been instructed in the way of the Lord, and being spiritually impassioned, he was speaking and teaching accurately the things about Jesus, though he knew only the baptism of John;

26and he began to speak boldly and fearlessly in the synagogue. But when Priscilla and Aquila heard him, they took him aside and explained more accurately to him the way of God [and the full story of the life of Christ].
