Matthew 19:24…And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God.
The eye of a needle mentioned by Jesus simply referred to a gate through the wall around Jerusalem. An awkward camel could kneel down and crawl, to enter through this gate. The eye of needle was a small gate through the wall that could hinder any enemy from entering quickly into Jerusalem. The eye of a needle is a literal gate not to be “spiritualized” in any sense.
In retrospect…The money changers had turned Israel’s Holy Temple into a den of thieves. The nation of Israel as a whole had deviated from God’s Torah and Commandments that kept Israel holy. Greed, lust, and immorality consumed many of the Jewish leaders and figures during the day of Christ because they had backslidden from the Torah, the Law of God. As Jesus rebuked these leaders a comparison was made between “The eye of the needle, the camel… and the rich and immoral Jewish leaders and the Kingdom on Earth promised to Israel”. Many of the rich at that hour were so consumed with the love of money and wealth, they could not recognize that Christ was the promised Messiah afore mentioned by the Prophets.
Without recognition of Christ no man could enter into the Kingdom promised to be established in Jerusalem. This promised Kingdom that was to be established under the Messiahship of Christ (who came at that time)…was promised by God from the foundation of the world.
