“It is written, “Cast your burden upon God, and He will sustain you” (Psalms 55:23)

If a human being has a patron and goes to him once, he is received.  The second time he is also received, but the third time, he is refused an audience.  By the fourth time, no attention is paid to him at all.

This is not true by God.  No matter how many times you bother Him, He receives you.” ~ Midrash Tehillim 55:6 as quote by R’ Aryeh Kaplan zt”l in A Call to the Infinite
