8 Then Paul went to the synagogue and preached boldly for the next three months, arguing persuasively about the Kingdom of God. 9 But some became stubborn, rejecting his message and publicly speaking against the Way. So Paul left the synagogue and took the believers with him. Then he held daily discussions at the lecture hall of Tyrannus. 10 This went on for the next two years, so that people throughout the province of Asia-both Jews and Greeks-heard the word of the Lord. 11 God gave Paul the power to perform unusual miracles. 12 When handkerchiefs or aprons that had merely touched his skin were placed on sick people, they were healed of their diseases, and evil spirits were expelled.

(Read Acts 19:8-12)
When arguments and persuasions only harden men in unbelief and blasphemy, we must separate ourselves and others from such unholy company. God was pleased to confirm the teaching of these holy men of old, that if their hearers believed them not, they might believe the works.
