My peace I give to you
Peace is a good to be promoted with good: it is a good for individuals, for families, for nations and for all humanity; yet it is one which needs to be maintained and fostered by decisions and actions inspired by good.
Sacred Scripture teaches that at the dawn of history Adam and Eve rebelled against God, and Abel was killed by Cain, his brother (cf. Gen 3-4). These were the first wrong choices, which were succeeded by countless others down the centuries. Each of these choices has an intrinsic moral dimension, involving specific individual responsibilities and the fundamental relationship of each person with God, with others and with all of creation.
No man or woman of good will can renounce the struggle to overcome evil with good. This fight can be fought effectively only with the weapons of love. When good overcomes evil, love prevails and where love prevails, there peace prevails.
John Paul II. 1 January 2005. 38th World Day of Peace
