Advent is the start of a new Church year for Christians.
Every new year signifies another chance to start anew. Hence it's good to start working on a clean slate. Take a look at this clean white artboard. Go ahead click on it.
And as you move your mouse on it, clicking and dragging, you can fill it with colors and figures your heart and mind could ever desire or imagine. Until you produce your very own artwork. Life is art they say. Such is life... it's in your mouse... ooops sorry, it's in your hands.
Advent is like clean artboard where you start to fill it little by little, step by step with colors and decors until at the end up with the most colorful artwork - Christmas.
