Concentration—Some have cultivated the habit of too great concentrativeness. The power to fix the mind upon one subject to the exclusion of all others, is good to a limited degree, but those who put the whole strength of the mind into one line of thought are frequently deficient on other points. In conversation these become tedious, and weary the listener. Their writings lack a free, easy style. When they speak in public, the subject before them holds their attention, and they are led on and on, to go deeper and deeper into the matter. They seem to see knowledge and light as they become interested and absorbed, but there are few who can follow them. (GW 169.1) MC VC

There is danger that such men will plant the seed of truth so deep that the tender blade will never find the surface. Even the most essential, manifest truths, those which are of themselves clear and plain, may be so covered up with words as to be made cloudy and indistinct. (GW 169.2) MC VC

Simplicity—Argument is good in its place, but far more can be accomplished by simple explanations of the word of God. The lessons of Christ were illustrated so clearly that the most ignorant could readily comprehend them. Jesus did not use long and difficult words in His discourses; He used plain language, adapted to the minds of the common people. He went no farther into the subject He was expounding than they were able to follow Him. (GW 169.3) MC VC
