Luke—the author of the third Gospel and the book of Acts—is of special interest for several reasons. He was the only Gentile who wrote any of the books of the Bible. Furthermore, he was the only scientist among the writers.

"And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years" (Genesis 1:14).

"And by Him all that believe are justified from all things, from which ye could not be justified by the law of Moses" (Acts 13:39).

"For thus saith the LORD that created the heavens; God Himself that formed the earth and made it; He hath established it, He created it not in vain, He formed it to be inhabited: I am the LORD; and there is none else" (Isaiah 45:18).

"Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed" (John 20:29).

Jesus was willing to give doubting Thomas the visible evidence he wanted before he would believe. However, He did give His disciple a mild rebuke.
