We had a BLAST from the past on Sunday! ❤️🙌🏼

We closed out our October Special Sundays in style with an Old School Sunday filled with hymns, throwback fashion, sermon note sheets, and so much more. We wrapped up our “Kingdom Acceleration” series and we can’t wait to kick off Missions Week next Sunday! 🌎

We are still in awe of all that God did at our Praise + Prayer Night! 🙌🎶 It was a powerful night of worship, prayer, and honoring the Lord right on our front lawn, at a busy intersection, in the midst of His creation.
