Matthew 19:24 “Again I tell you, it is easier for a camel to go through the eye of a needle than for someone who is rich to enter the kingdom of God.”
The bible has some hard teaching about money. Wealth can be spiritually damaging. Living in a wealthy country like the USA it is possible to accumulate such wealth as can be dangerous to ones soul. I believe a multimillion dollar house isn’t a neutral choice – it is a sin issue. With the kind of need in the world you cannot simply buy a multimillion dollar house and ignore the suffering in the world as if it is not of significance. Ignoring the suffering (spiritual and material) is not an issue if we wish to follow Christ as we should. There is a major ethical dimension to how we spend the money we have.
