The eyes of the LORD are on the righteous
and his ears are attentive to their cry;
Psalm 34:15 (NIV)
God is watching.
He sees everything that we are going through. Nothing escapes His attention. When we cry out to Him, He hears us. Even when our prayers don't seem to reach beyond the ceiling... it doesn't matter, they don't need to reach beyond any ceiling, in fact, they don't even need to pass beyond our own lips. He hears even when no one else can.
