"There is a...fulness of faith that we should strive unto, and of knowledge as well as of holiness: For this life is our way to heaven, and still we must draw nearer thitherwards, by knowing all that we can know by the Word, Deut 29:29" (The Scripture's Sufficiency)
It is important to not that Twisse is evidently not referring to mere head knowledge but knowledge of how to glorify and enjoy God from the only rule to direct us how we may do this.
Phillipians 3:13ff.
