Lean on the Holy Spirit!
Jesus promises that the Spirit will guide us into truth. That means we always have more to learn. It also means we depend on the Spirit and each other - because the Spirit so often speaks to us through others. Being a community that worships in the name of the Father, and of the Son, and of the Holy Spirit means that we know we don't have all the answers and we value people who bring different voices and experiences into the mix. You belong here! So does your friend. Invite them to come.
May the Peace of the Lord be yours,
