Our Services

What are services like?
We begin with a "healthy" food and fellowship at 10:15am, then move into the sanctuary for our celebration experience. We worship to contemporary style music, leaving many openings for the Holy Spirit to use people, young and seasoned to lives will be touched. At some point we will take up an offering to meet budget and outreach needs. A key point, of course, is study in the Word, so we will spend time exploring God's word together, sometimes with the help of PowerPoint and multimedia.

What is the community like?
Very fun loving, in the midst of dealing with serious issues in the lives of people, we love to have get together and laugh, and have a good time!

What if I'm not a Christian?
You are welcome! It is are desire to create a sense of belonging before believing.
