In his Sermon on the Mount (Matthew 5-7), particularly in Matthew 6:25-34, why in addition to the very basic human need for food, drink, and clothing did Jesus not include the need for shelter?
The argument could be made that because Israel is in a subtropical climatic zone, shelter was simply not as necessary as it was and is today, particularly in the harsher and colder climatic zones, especially in the continental, polar, and alpine climates.
Jesus was certainly not opposed to the ownership of land and houses. We assume that Jesus grew up in a house, and the gifts of the Magi may very well have provided Joseph and Mary with funds with which to purchase a house.
Moreover, Jesus's life was made easier both before and during his public ministry by having a house in which to reside (see Matthew 2:11 and 4:13; Mark 2:1, 2:15, and 9:28; John 1:39 and 2:11). He also stayed frequently at the home of Mary, Martha, and Lazarus, and he may have lived for a time with Simon Peter and Peter's wife and mother-in-law.
I find strange that Jesus did not include housing as one of the worries that plague humankind. Granted, there was a time in Jesus's public ministry when "the Son of Man had nowhere to lay his head" (Matthew 8:20), but Jesus's nomadic lifestyle in the last three years of his life likely required pitching a tent or sleeping under the stars when no house was available.
The apostle Paul certainly faced privation. He had to forgo some basic necessities from time to time, such as food and shelter (see Philippians 4:10-12), clothing (see 2 Timothy 4:15), and safety and well being (his beatings, his shipwreck, and more). He still could say with complete confidence:
I can do all this through him who gives me strength(4:13).
Moreover, he could also to the Philippian believers with full confidence,
And my God will meet all your needs according to the riches of his glory in Christ Jesus (4:19, with my bolding).
A small irony attaches to that verse since there are times when believers are called by God to be in need. In other words, one of our needs is to be in need. God sometimes teaches us and matures us through deprivation. The apostle Paul realized this, and while he enjoyed--I surmise--having plenty, he would accept living in want and be content either way.
