The Apostle Paul said:

Command those who are rich in this present world not to be arrogant nor to put their hope in wealth, which is so uncertain, but to put their hope in God, who richly provides us with everything for our enjoyment.  Command them to do good, to be rich in good deeds, and to be generous and willing to share.  In this way they will lay up treasure for themselves as a firm foundation for the coming age, so that they may take hold of the life that is truly life. (1 Timothy 6:17-19, NIV)

According to Randy Alcorn:

If you have:

sufficient food,
decent clothes,
live in a house or apartment,
and have a reasonably reliable means of transportation,
you are among the top 15 percent of the world’s wealthy.

If you have:

any money saved,
a hobby that requires some equipment or supplies,
a variety of clothes in your closet,
two cars (in any condition),
and live in your own home,
you are in the top 5 percent of the world’s wealthy.

(Money, Possessions, and Eternity)

Jesus said:

I tell you the truth, it is hard for a rich man to enter the kingdom of heaven. Again I tell you, it is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God. (Matthew 19:23-24, NIV)
