Augustine, On the Trinity, 1.5

In “What Augustine Requests from His Readers”:

Yet, for my part, I meditate in the law of the Lord, if not day and night, at least such short times as I can; and I commit my meditations to writing, lest they should escape me through forgetfulness; hoping by the mercy of God that He will make me hold steadfastly all truths of which I feel certain; but if in anything I be otherwise minded, that He will himself reveal even this to me, whether through secret inspiration and admonition, or through His own plain utterances, or through the reasonings of my brethren. This I pray for, and this my trust and desire I commit to Him, who is sufficiently able to keep those things which He has given me, and to render those which He has promised.
