Passage
that thou mightest know the certainty of those things in which thou hast been instructed.
that thou mightest know the certainty of those things in which thou hast been instructed.
Luke 1:2 as those who from the beginning were eye-witnesses of and attendants on the Word have delivered them to us,
Luke 1:3 it has seemed good to *me* also, accurately acquainted from the origin with all things, to write to thee with method, most excellent Theophilus,
Luke 1:4 that thou mightest know the certainty of those things in which thou hast been instructed.
Luke 1:5 There was in the days of Herod, the king of Judaea, a certain priest, by name Zacharias, of the course of Abia, and his wife of the daughters of Aaron, and her name Elizabeth.
Luke 1:6 And they were both just before God, walking in all the commandments and ordinances of the Lord blameless.
The verse centers on "thou", "mightest", "certainty", "things", "hast", "been", and "instructed". It is saying that the verse draws attention to "thou" and "mightest", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "it has seemed good to me also..." into verse 5's "There was in the days of Herod...", so "thou" and "mightest" belong inside that flow. In Luke context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "thou" and "mightest" with trust shaped by these words, not by a vague optimism outside the passage.
