What does the Bible say about the joy of Christ's birth?

The Bible highlights that the birth of Christ brings immense joy, particularly for those who recognize their need for salvation. In Isaiah 9:2, it states, 'the people that walked in darkness have seen a great light,' signifying that the advent of Jesus is a source of joy for His people. The joy is akin to a bountiful harvest or the celebration of victory after battle, as the coming of Christ represents the fulfillment of God's promise to deliver and redeem those who dwell in the shadow of death.
