There's many times that the New Testament says that it's easier for a camel to go through the eye of a needle than a rich people to enter to the kingdom of God.
There is nothing in the scripture that specifically states that rich people cannot enter into Heaven. Understand the intent behind what Jesus said when he said that it was easier for a camel to pass through the eye of a needle than for a rich man to enter Heaven.
What Jesus was saying was that because rich men trust in their riches, they think they have no need of God, much less any need to repent of their sins. The rich young ruler who said he wanted to follow Jesus did not follow him because he placed more trust in his wealth than he did in Jesus.
It is the trust in the riches that the wealthy have that keeps them out of Heaven, but let us also remember that Joseph of Arimathea was a man of wealth and yet a disciple of Jesus. Was it not a rich man’s tomb in which the body of Jesus was placed. And was it not from the tomb of a man of wealth that Jesus was raised from the dead?
Wealthy people need Jesus every bit as much as the poor. It’s just that the circumstances of the poor cause them to be more reliant on something higher than themselves and therefore tend to be more receptive to the Gospel than the rich who are not as likely to give the message of the Gospel the time of day because the abundance of their wealth blinds them to their need for God and to their sin.
It takes a lot for a person of wealth and power to place his or her trust in the Lord in comparison to someone who is not a person of wealth. Bear in mind also that Jesus did not condemn wealth in and of itself. He simply said that the trust therein is what keeps the rich out of Heaven, but that doesn’t mean that it is not impossible for a rich person to be persuaded to place their trust in Christ.
But if I were to go to a certain place to preach the Gospel, I would first go out to those whom I know would be the most receptive and they would be the people who are neither wealthy, hold positions of power or influence, nor possess credentials, but if one possessing wealth, power, influence, or any set of credentials were to come to me in their search for God, I certainly am not going to turn them away because Jesus would not.
He died for the sins of all men; rich and poor, renown and unknown, the educated and uneducated, the ruler and the subject, male and female, people of every color, ethnicity, nation, walk of life, of every background and of every age.
Remember also that the early church was also made of people from every walk of life and the Gospel was spread to all people no matter who they were or what their station in life was. Even the Apostles were a diverse lot.
