The Kingdom of God is a space. It exists in every home where parents
and children love each other. It exists in every region and country
that cares for its weak and vulnerable. It exists in every parish
that reaches out to the needy.
The Kingdom of God is a time. It happens whenever someone feeds a hungry person, or shelters a homeless person, or shows care to a neglected person. It happens whenever we overturn an unjust law, or correct an injustice, or avert a war. It happens whenever people join in the struggle to overcome poverty, to erase ignorance, to pass on the faith.
The Kingdom of God is in the past (in the life and work of Jesus of Nazareth); it is in the present (in the work of the Church and in the efforts of many others to create a world of goodness and justice); it is in the future (reaching its completion in the age to come).
The Kingdom of God is a condition. Its symptoms are love, justice, and peace.
Jesus Christ is king! We pray today that God may “free all the world to rejoice in his peace, to glory in his justice, to live in his love.”
Jesus enters human history as God’s anointed son who announces the nearness of the reign of God (Mk 1:9-14). This proclamation summons us to acknowledge God as creator and covenant partner and challenges us to seek ways in which God's revelation of the dignity and destiny of all creation might become incarnate in history. It is not simply the promise of the future victory of God over sin and evil, but that this victory has already begun—in the life and teaching of Jesus.
