Change in stance?

In the second Canto, Sage Suka tells Parikshit that one should go in search of satsang and Guru. He also says that one should renounce his house, and belongings. Are there no shelters provided by nature? Will you not get rags on the street that you can drape? Will not the trees give you fruits to satisfy your hunger? Will not the rivers give you water to quench your thirst?
Interestingly, here he says, God has this principle of taking care of anyone who has surrendered unto Him. Has God changed this stance of His?
