In order to bring peace to others we need to be first grounded in it our own hearts. Peace comes from order, from a well-ordered life, one lived where everything is directed toward God. When all disorder is removed from the heart and all our desires, thoughts, words and deeds are fully ordered toward God following His commands, doing His will, then we possess peace and radiate peace to others.
Once we posses this peace, continue to take care to remain in this peace, and spread peace to those around us – we can be called a peacemaker.
Nothing disturbs a peacemaker because a peacemaker knows that all things are permitted by God and work out for our good.
To cultivate peace and become a peacemaker we need to persevere in prayer, that intimate dialogue with God, and surrender completely with trust to His Holy will.
The fruit of this relationship with God is a calm interior peace, seeing God in all things, even hardships and suffering without being disturbed or upset, and with the ability to see God in all. Another fruit of this peace is seen in relationship with others. All are seen as children of God, all are loved and the peaceful soul wishes good to all and wants to live in peace with them.
“Our God is the God of peace; therefore, it is perfectly right that the peaceful man, he who possess and diffuses peace, should feel in a very special way that he is God’s child. If men generally do not feel themselves to be children of God, it is because they are so little disposed to peace, so ready for disputes, quarrels and war. They talk about peace but do not make peace, for they do not accept the guidance of the Spirit of Wisdom. In their ignorance they prefer to be guided by themselves, and as a result they are dominated by pride, self-interest, and cupidity; they live in disorder and they sow disorder around them.
The more our soul becomes firmly established in peace, and the more we become messengers of peace, to that degree will the Holy Spirit infuse into us this delightful sense of our divine sonship and this will become for us a source of immense happiness, a true prelude to eternal beatitude.” (Divine Intimacy, #314, Fr. Gabriel of St. Mary Magdalen, OCD)
“Blessed are the peacemakers, for they shall be called sons of God” (Matt 5:9)
