It's wonderful to see unity by the Spirit. This joins truth and love together in Jesus among ourselves. Humility is at the forefront here. Humility is simply having that sense of who we are, good and bad, and seeing others as just as valuable or important as ourselves, and treating them as more so.
I saw this yesterday in our team at work. A good atmosphere of love and respect for each other, in reverence for the Lord.
From this we can do the will of God in Jesus, for each other and in mission for the world. And without this we can do none of it, at least not very well.
What thoughts might you have about "unity in love"?
