I used to be spiritually minded but am now materialistic. It’s a better way to live in my opinion. We are material people living in a material world. We stay alive by eating organic material. Our entire reality is material. All the while we dwell on this planet we will seek comfort in material things. It is our nature to be materialistic. Who is to say what constitutes being ‘excessively’ concerned with material possessions?
The reason various religious leaders caution against being materialistic, is that it is a distraction from supporting their particular persuasion. They earn their living by directing people towards heaven, earthly activity is discouraged. They have cleverly retagged materialism as ‘greed’ and called it a deadly sin. Oh please!
