What season of the Church focuses on our waiting for the kingdom of God to come in its fullness?

The season of Advent in the Church focuses on our waiting for the kingdom of God to come in its fullness. It is a time of preparation and anticipation for the celebration of Christmas, commemorating the birth of Jesus Christ, while also looking forward to His second coming. Advent invites believers to reflect on their spiritual readiness and to embrace hope, joy, and expectation in the promise of God's future fulfillment.
