IV. It is also of the greatest importance to meditate on what we read, so that perhaps a small portion of that which we have read, or, if we have time, the whole may be meditated upon in the course of the day. Or a small portion of a book, or an epistle, or a gospel, through which we go regularly for meditation, may be considered every day, without, however, suffering oneself to be brought into bondage by this plan. Learned commentaries I have found to store the head with many notions, and often also with the truth of God; but when the Spirit teaches, through the instrumentality of prayer and meditation, the heart is affected. The former kind of knowledge generally puffs up, and is often renounced, when another commentary gives a different opinion, and often also is found good for nothing, when it is to be carried out into practice. The latter kind of knowledge generally humbles, gives joy, leads us nearer to God, and is not easily reasoned away; and having been obtained from God, and thus having entered into the heart, and become our own, is also generally carried out. If the inquirer after truth does not understand the Hebrew and Greek languages, so as to be able to compare the common translation with the original, he may, concerning several passages, get light by an improved rendering, provided he can be sure that the translator was a truly spiritual person. The last and most important means of, grace, namely, prayer, was comparatively but little improved by me. I prayed, and I prayed often. I also prayed, in general, by the grace of God, with sincerity; but had I been more earnestly praying, or even only as much, as I have prayed of late years, I should have made much more rapid progress.
