Above all, clothe yourselves with love, which binds everything together in perfect harmony.
And let the peace of Christ rule in your hearts, to which indeed you were called in the one body. And be thankful. Colossians 3.14, 15
The peace of Christ, which we proclaim and live, is not an abstract, distant peace, It’s not the dream and hope of a peaceful world where all will one day be in harmony with each other, preferably sharing some kind of carbonated beverage. The peace we share is rooted and grounded in the love of God. Love which is for and from the Divine. There are very few definitive statements made about God even in scripture - most live in the realm of poetry and analogy, but there is one book of Scripture that sums up the very nature of God - the First Letter of St John, Chapter Four, verse 16 - “God is Love, and those who live in love live in God and God lives in them.”
This love is not sickly, or soppy or romantic love (though that kind of love does offer an echo of Divine love) - the love of God is hard edged, powerful, compelling; a love which forgives, loves, embraces, even those who are considered or who feel, unlovely and unloveable, This is a love that is fierce as the grave, as powerful as the ocean - a love unafraid to commit to the best for others, whether we feel they deserve it or not. It’s a love given freely and without limits - which the Bible calls Grace.
When that love is alive in us, we can become the people of peace we are called to be.
