Jonah's went down and Jesus's humility
The prophet Jonah, who disobeyed God's command, went down to Joppa
and even further went down on a ship to Tarshish (Jonah 1:3),
went down to the lower deck of the ship (1:5),
and ultimately went down to the depths of the sea (2:3)
and to the roots of the mountains (v. 6).
However, Jesus, who obeyed God's will, did not consider equality with God
something to be grasped (Phil. 2:6),
came down to this lowly world in the form of sinless human flesh,
born in a lowly manger in Bethlehem (Lk. 2:7),
took the very nature of a servant, being made in human likeness (Phil. 2:7),
made himself nothing (v. 7), and even went to the extent of dying on the cross (v. 8),
bearing the cross's humiliation only to the lowest depths,
and Jesus descended lower and lower, even in the heart of the earth (Mt. 12:40).
