If you are in conflict with another brother or sister in Christ, this should not sit right with you. You should be troubled by this. If you are a follower of Jesus, you must do something about it.
You will not have peace with God if you are not working towards peace with others. The very peace Jesus promises to all who abide in him is not only for you. It is for the community of Jesus-followers you are in.
Henri Nouwen, in his beautiful book The Road to Peace, writes:
"In his farewell discourse Jesus said to his apostles, "Peace I leave to you, my peace I give to you; a peace the world cannot give, this is my gift to you" (John 14:27). When we want to make peace we first of all have to move away from the dwelling places of those who hate peace and enter into the house of him who offers us his peace. This entering into a new dwelling place is what prayer is all about." (9)
"In his farewell discourse Jesus said to his apostles, "Peace I leave to you, my peace I give to you; a peace the world cannot give, this is my gift to you" (John 14:27). When we want to make peace we first of all have to move away from the dwelling places of those who hate peace and enter into the house of him who offers us his peace. This entering into a new dwelling place is what prayer is all about." (9)
A peacemaker dwells, not in the house of fear and war, but in the house of peace. In Christ, there is peace. As I abide in Christ he gives me his peace, a peace that is different from this world's peace. I connect with him who is our peace. (Ephesians 2:14) How?
By praying. Praying is a main way of connecting to God. Have an actual praying life and receive the peace of God, as Jesus promised. "A peacemaker," writes Nouwen, "prays."
He continues: "Prayer is the beginning and the end, the source and the fruit, the core and the content, the basis and the goal for all peacemaking. I say this without apology, because it allows me to go straight to the heart of the matter, which is that peace is a divine gift, a gift we receive in prayer." (9, emphasis mine)
In some church communities the people do something called "passing the peace." They turn to people next to them, and say, "The peace of the Lord be with you." The peace of God is something for others. You have been freely given God's peace. So, freely give it away. Which means, make peace with others.
Jesus didn't give us the Beatitudes so we could posterize them. (Matthew 5) Real followers of Jesus live these things out. Division doesn't sit right with them.
This is hard work. It is out of our comfort zones. Nearly everything Jesus calls us to do is out of our comfort zones. This is why peace-lovers are many, but peacemakers are few.
If you follow Jesus, you will wage peace. You will then experience the blessing and favor of God, imparted like anointing oil, over you.
How good and pleasant it is
when God’s people live together in unity!
It is like precious oil poured on the head,
running down on the beard,
running down on Aaron’s beard,
down on the collar of his robe.
It is as if the dew of Hermon
were falling on Mount Zion.
For there the Lord bestows his blessing,
even life forevermore.
Psalm 133:1-3
