Why is it that some Christians make it taboo to speak on money in a positive light? Anytime a Christian speaks on how God blessed them financially, they become a crook in the eyes of the public. It seems like the rest of the world can be blessed and rich but, us Christians have to be content and live on the bare minimum. Where did we get this idea that the more poor we are, the more spiritual we become?

That is not the Word of God.

The wealth God has for His people is immeasurable. There are many verses in the Bible where God desires to bless His people and His people only.
Just to name a few…
Proverbs 13:22 A good man leaves an inheritance for his children’s children, but a sinner’s wealth is stored up for the righteous.

Psalm 37:25 I was young and now I am old, yet I have never seen the righteous forsaken or their children begging bread.

Psalm 112:3 Wealth and riches will be in his home. His righteousness continues forever.

Acquiring money honestly is not the only thing God desires for us but, it is one of many. Receive your inheritance and be wealthy.
