As they were going along the road, someone said to him, “I will follow you wherever you go.” And Jesus said to him, “Foxes have holes, and birds of the air have nests, but the ( has nowhere to lay his head.”Luke 9:57-58, ESV)
Miyamoto Musashi wrote 'The Way of the Warrior' and Book of Five Rings, he was a man who lived his entire life in pursuit of perfecting his skills as a samurai. Instead of setting down roots in any one place he picked up and moved on when he felt he had learned everything that he could where he was at the time. Our Lord Jesus also never had a place to call His own once He embarked upon His time of ministry. He was about spreading the Word and proclaiming the Kingdom of God. Both men (and i am not relating these two examples as equals) pursued their purpose in life with nothing to hold them back. When one has a home it tethers one to a location and makes it more difficult to move from region to region as needed. Jesus advised a rich young ruler, “If you would be perfect, go, sell what you possess and give to the poor, and you will have treasure in heaven; and come, follow me.” (Matthew 19:21, ESV)
To be unfettered in this life to freely and perfectly follow Jesus, possessions are responsibilities that are detracting from the eternal. But before a reader goes out and sells everything without thought i would also remind you that Paul followed up in 1 Corinthians 7 with:
So, where you find yourself on the path of following God "seek first the kingdom of God and His righteousness".
Only let each person lead the life that the Lord has assigned to him, and to which God has called him. This is my rule in all the churches. Was anyone at the time of his call already circumcised? Let him not seek to remove the marks of circumcision. Was anyone at the time of his call uncircumcised? Let him not seek circumcision. For neither circumcision counts for anything nor uncircumcision, but keeping the commandments of God. Each one should remain in the condition in which he was called. Were you a slave  when called? Do not be concerned about it. (But if you can gain your freedom, avail yourself of the opportunity.) For he who was called in the Lord as a slave is a freedman of the Lord. Likewise he who was free when called is a slave of Christ. You were bought with a price; do not become slaves of men. So, brothers,  in whatever condition each was called, there let him remain with God. (17-24, ESV)
