Acts 14:1 "Now at Iconium they entered together into the Jewish synagogue and spoke in such a way that a great number of both Jews and Greeks believed."
They spoke in such a way.
It matters how we speak. Our presentation can have an effect on whether or not someone believes.
This does not mean that it all depends on us. It's also up to the person we are speaking to, and to God. But our part matters.
How our music sounds matters. How our movies look matters. How we write matters. How we speak matters. Our grammar matters. Our reasoning matters. The quality of what we make matters.
Those things aren't absolute. They don't matter most, but they matter.
Do you agree?
