For Christians, Christmas holds deep religious meaning as it signifies the birth of Jesus Christ. Christmas is an annual holiday that is celebrated by billions of people, religious or otherwise, throughout the world on December 25.
Jesus Christ is the central figure of Christianity and is believed to be the Son of God - that is, Christians believe Christ to be fully human and fully God. Christmas is a holiday that celebrates his birth, as it is outlined in the in the canonical gospels of Matthew and Luke, which are found in the New Testament of the Christian Bible.
It is believed that through the life, death and resurrection of Jesus Christ, humans can be reconciled to God and offered salvation in Christ and eternal life. While that completes the story of Christ, the beginning is still of utmost importance. As a result, Christians celebrate Christmas as a way to commemorate the beginning of his life on Earth.
While both Christians and non-Christians celebrate Christmas as a holiday by giving gifts and spending time with loved ones, many Christians also prepare for Christmas during the Advent season. Advent, which commences on the fourth Sunday before Christmas is often spent as a time of expectant waiting as they spiritually prepare themselves to celebrate the birth of Christ.
