"do not worry about how or what you should speak"

C.H. Spurgeon relates the following in Lectures To My Students in the chapter entitled 'On the Choice of the Text:

"do not be misled by the sound and seeming fitness of scriptural words. M. Athanase coquerel confesses to having preached on a third visit to Amsterdam, the words, "This is the third time I am coming to you." (2 Cor. 13:1)... It is still worse to select words out of a miserable facetiousness, as in the case of a recent sermon on the death of Abraham Lincoln, from the sentence, "Abraham is dead."
