Matthew 6:24 (KJV)
No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.
The biblical frame of reference for wealth is that God is the source of all gain. I think money can be bad when it takes the place of God in your life as your provider.
Abraham and Job did have wealth but it all came from God. Even the silver and gold is from God. It wasn't man made.
Genesis 13:2King* (KJV)
And Abram was very rich in cattle, in silver, and in gold.
When we put our faith in money to provide us food, buy us health from Dr's, providing shelter and heat, we tend to think that's all we need and we* don't look to Elohim to give us rain for food or anointing for health..etc..
