Make every effort to keep the unity of the Spirit through the bond of peace.
If possible, so far as it depends on you, live peaceably with all.
1. What causes gaps?
Distance breeds distrust
But now in Christ Jesus you who once were far away have been brought near by the blood of Christ. For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility….
Relational chasms start out as relational cracks
2. What goes in the gap?
So if you are presenting a sacrifice at the altar in the Temple and you suddenly remember that someone has something against you, leave your sacrifice there at the altar. Go and be reconciled to that person. Then come and offer your sacrifice to God.
My dear brothers and sisters, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry, because human anger does not produce the righteousness that God desires.
Why do you see the speck that is in your brother’s eye, but do not notice the log that is in your own eye?
For by the grace given me I say to every one of you: Do not think of yourself more highly than you ought, but rather think of yourself with sober judgment, in accordance with the faith God has distributed to each of you.
“Brother, if any man thinks ill of you, do not be angry with him; for you are worse than he thinks you to be. If he charges you falsely on some point, yet be satisfied, for if he knew you better he might change the accusation, and you would be no gainer by the correction. If you have your moral portrait painted and it is ugly, be satisfied; for it only needs a few blacker touches and it would be still nearer the truth.” - Charles Spurgeon
The good news isn’t really good, until the bad news is really bad
3. Standing in the gap
I looked for someone among them who would build up the wall and stand before me in the gap on behalf of the land so I would not have to destroy it, but I found no one.”
So from now on we regard no one from a worldly point of view. Though we once regarded Christ in this way, we do so no longer. Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here! All this is from God, who reconciled us to himself through Christ and gave us the ministry of reconciliation: that God was reconciling the world to himself in Christ, not counting people’s sins against them. And he has committed to us the message of reconciliation. We are therefore Christ’s ambassadors, as though God were making his appeal through us. We implore you on Christ’s behalf: Be reconciled to God. God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.
