Tips for playing the sermon videos:

From the Embedded Video File above:

Click play, then click the Full Screen option located at the far right of the video.

This will allow the video to fill the entire screen for easier viewing.

From the Google Drive:

If your computer requires you to first download videos before viewing the sermons, you can install Mozilla Firefox.  It is a free browser and is easy to install from the internet to your computer.

Once installed, simply access the church website through Firefox.
