Please realise what Infinite Power means.
Infinite Power created the stars and maintains them in their courses. Does that give you some conception of Infinite Power? Think it well over, and try to realise it.
Having realised it, you will realise also that it must, of necessity, be more than adequate to deal with your petty troubles and obstacles. If you are honest with yourself, you must recognise that a power that can control millions of planets will not be baffled, let alone beaten, by such conditions as surround you.
So the first thing to do is to get a clear conception of the absolute fact that there is an Infinity of Power available.
