Praying and planning will never do together. If I plan, I am leaning more or less on my plan; but when I pray, I should lean exclusively upon God. Hence, the two things are perfectly incompatible—they virtually destroy each other.
No doubt, when faith allows God to act, He will use His own agency; but this is a totally different thing from His owning and blessing the plans and arrangements of unbelief and impatience. This distinction is not sufficiently understood.
