Does He hear you?

Psalm 116:1-2
I love the Lord, he heard my voice; he heard my cry for mercy. Because he turned his ear to me, I will call on him as long as I live.

Do you know that the Lord hears you? He knows your pleas, he knows your problems, he knows your sins, he is the Lord Jehovah Shammah, the one who is present.

This verse reminds me of several debates I've had about the Lord hearing prayers. Does he hear ALL our prayers? What if your cry for mercy is not for something that is according to His will. For example, does he hear your cry to Him to win the lottery?

I think he hears my voice, as long I pick up the right phone!
