What does Chapter 39 reveal about the purpose of Sai Baba's incarnation and his concern for his devotees?

Chapter 39 of the Shri Sai Satcharitra explains that Sai Baba's incarnation was driven by a "great concern for the upliftment of his devotees." The text asserts that he came to Shirdi of his own accord for this very purpose, with Chand Patil being merely an instrument in this divine plan. The chapter further elaborates on the beneficiaries of his grace, questioning who else but Sai would uplift the "dull-witted, the fallen, and the poor, those without vows, penance, or sacraments—simple and faithful people." This highlights his mission to guide and elevate all who approached him with simple faith.
