Foxes having holes and birds having nests allude to the imperial family and its domain-- the basic hierarchical unit of society--that provided food, clothing, shelter, safety, security, and honor. Those who follow the "homeless" Son of Man are members of a different oikos, God’s oikos where widows, orphans, and strangers are the most privileged and where even the most unwelcome is always welcome. Yes, even beggars.
Burial rites are again part of the rituals and obligations of the imperial family. Going and proclaiming good news to the poor, release to the captives, recovery of sight to the blind, to let the oppressed go free, and to proclaim the year of the Lord’s favor, God's jubilee of justice, takes priority.
Anyone who has put a hand to the plow knows that looking back is unacceptable. The one who has decided to become a farmer in the Kingdom of God but yearns to go back to farming for the Kingdom of Rome, the complete opposite direction, is not fit to follow Jesus.
The song we learned in Sunday School is true. There is no turning back.
Those who think that following Jesus of Nazareth is easy, rewarding, and will bring us closer to heaven are following the wrong Jesus.
