When you were fourteen did you know where all the means were coming from which were going to support you till now when you are perhaps forty or fifty?
So you should argue that the same power that has worked in the past can continue to work in the future.

If you say the means came in the past quite naturally through ordinary channels, that is no objection; on the contrary the more reason for saying that suitable channels will open in the future.

Do you expect God to put cash into your desk by a conjuring trick?
Means come through recognizable channels, that is to say we recognize the channels by the fact of the stream flowing through them; and one of our most common mistakes is in thinking that we ourselves have to fix the particular channel beforehand.

We say in effect that the Spirit cannot open other channels, and so we stop them up.

Or we say, our past experience speaks to the contrary, thus assuming that our past experiences have included all possibilities and have exhausted the laws of the universe, an assumption which is negatived by every fresh discovery even in physical science.
