When you are reading your Scriptures in this way—it matters not whether you have read little or much—if a verse stands out and hits you and arrests you, do not go on reading.
Stop immediately, and listen to it.
It is speaking to you, so listen to it and speak to it.
Stop reading at once, and work on this statement that has struck you in this way.
Go on doing so to the point of making a skeleton of a sermon. This verse or statement has spoken to you, it has suggested a message to you.
The danger at that point I had to discover is to say to oneself, ‘Ah yes, that is good, I will remember that’, and then to go on with the reading.
Then you find yourself towards the end of the week without a sermon for the Sunday, without even a text, and you say to yourself, ‘Now what was that that I was reading the other day? Oh yes, it was this verse in that chapter.’ You then turn back to it and find to your dismay that it says nothing at all to you; you cannot recapture the message.
That is why I say that whenever anything strikes you you must stop immediately and work out a skeleton of a sermon in your mind. But do not stop even at that: Put it down on paper.
