We do many things in the life we've been given to seek God's favor, even to fasting which many relate to denying food to sort of put God in a corner so that He has to answer. Isa 58:4 . . to make your voice to be heard on high.
Have you really come to the point in your life that you think God has somehow failed or forsaken you? No Yosef, you have gifts evidently undiscovered, and a mission only you might perform.
Isa 58:6 Is not this the fast that I have chosen? to loose the bands of wickedness, to undo the heavy burdens, and to let the oppressed go free, and that ye break every yoke?
Isa 58:7 Is it not to deal thy bread to the hungry, and that thou bring the poor that are cast out to thy house? when thou seest the naked, that thou cover him; and that thou hide not thyself from thine own flesh?
