It is often said that God helps those who help themselves, some people joke that's what Sarah and Abraham believed when she gave him Hagar.
But the good news is that God helps the helpless who cry out to Him. His grace is not unconditional in the sense that even those who do not respond receive it, but it is unconditionally in the sense that it is not given as a payment to any human ability or attempts to bargain with God, but to all who are willing to receive it His way.
*Edited for clarity. The 2nd sentence of the 2nd paragraph used to read "...even those who do nothing receive it".
