Mark 9:29

Mark 9:29. This kind can come forth by nothing, but by prayer and fasting.

God does not give us everything in answer to one prayer. It may be necessary for some blessings that the prayer should be reiterated - that it should deepen - that it should grow into an aching. It may be even necessary, in order that a blessing should come, that fasting should be used with prayer in order to show the intense eagerness and earnestness of the petitioner.

Now notice the 38th verse.
