Knox Presbyterian Church periodically holds Faith in Action Days to complete group service and work projects around the church. Projects have included:
- planting a native plant butterfly garden to provide pesticide free nectar sources for pollinators,
- weeding and mulching at Thomas Jefferson Library,
- making brownies and assembling snack kits for the local homeless shelter,
- assembling hygiene kits and school kits with distribution worldwide for Church World Service, and
- creating greeting cards with stamped envelopes for veterans to send to their families and friends.
Sometimes there have been church cleaning projects as well.
