A Christmas tree is a symbol of the birth of Jesus Christ and the Christian faith. It represents the Tree of Life, which is said to have provided the means for Adam and Eve to gain knowledge and wisdom. It also represents the Tree of Good and Evil, which was used to test Adam and Eve's obedience to God's command not to eat from it. In the Christmas story, the Tree of Life is said to have been adorned with gold and precious stones as a symbol of the wealth and beauty of the new kingdom of God.
