Acts 18:4 KJV
And he reasoned in the synagogue every sabbath, and persuaded the Jews and the Greeks.
Acts 18:28 KJV
For he mightily convinced the Jews, and that publickly, shewing by the scriptures that Jesus was Christ.
I found the word persuaded several times in chapters 18 and 19 of the book of Acts. Someone said that the only real leadership a Christian has is the leadership of persuasion. We persuade men and through persuading them, we lead them.
But there can be more than one way to persuade.
Some persuade through intimidation
Some persuade through skillful speaking
Some persuade through charisma
The only godly way for a Christian to persuade men is through the Scriptures and, specifically by showing "by the Scriptures that Jesus was Christ."
Anything else is wood hay and stubble.
