Luke 1:1-4 KJV

1 Forasmuch as many have taken in hand to set forth in order a declaration of those things which are most surely believed among us,
3 It seemed good to me also, having had perfect understanding of all things from the very first, to write unto thee in order, most excellent Theophilus,
4 That thou mightest know the certainty of those things, wherein thou hast been instructed .
