Hashem knows what we need even before we do, and prepares the solutions to our problems even before we become aware of them.  However, because He loves us so much, He does not provide the solutions until we ask.  Building a relationship with G-d is even more important than obtaining what we want, and Hashem therefore waits for us to cry out to Him and ask Him for help so we can draw closer to Him and build our relationship ~ Divrei Chizzuk
