The LORD is my shepherd, I shall not be in want. He makes me lie down in green pastures, he leads me beside quiet waters, he restores my soul. He guides me in paths of righteousness for his name's sake. Psalms 23:1-3
When you put your faith in Christ, you also have knowledge that he is there for you, that you will never be in want. It is the ultimate peace in knowing that no matter what happens God will provide.
