Keep us in the fellowship of your love, O God. Amen.
A keystone is the stone in the center of an arch that holds the whole thing together. The tension from all the different angles meet in that stone, which gives the arch its strength and stability. In other contexts such as organizations, ecology, or ideas, a keystone is something that is a central principle or thing on which everything else depends. Well, when it comes to our Christian faith, today’s reading from First John presents us with the keystone of our understanding of God and ourselves – God is love.
