In box #17 there is a rock to symbolize us kneeling on the ground in response to Jesus as God.
"Come, let us bow down in worship,
let us kneel before the Lord our Maker;
for he is our God
and we are the people of his pasture,
the flock under his care."
Jesus, came as a baby, but fully God and fully man. He is the King of King and Lord of Lords. Our response to him is to humble ourselves and worship him.
