Settling every Bible based question or studying every Bible based topic can hardly be resolved with a single verse every time, but there are times when a single verse is so clear and concise in what is being said, the point cannot be missed by any honest Bible student.
For example, take the question and topic of Jesus and his nationality. Due to their racist disposition, some people deny the “Jewishness” of Jesus. While the attitude may not be corrected, the argument can easily be defeated by something that Jesus said about himself.
While discussing topics of a spiritual nature, Jesus responded to a question that revolved around religious and national perspectives with, “You worship what you do not know; we know what we worship, for salvation is of the Jews.” (John 4:22 NKJV)
Being Jewish, in and of itself, does not make one right with God. Neither does being Jewish make one wrong with God. But saying that Jesus was not Jewish due to a personal disdain toward an entire race of people creates a mindset that ignores the heart of the matter, as well as an attitude of ignoring the plain language of the scriptures that will spread to other topics.
