Faith is a prosperous spirit; faithlessness is poverty. People do not need to center on prosperity for it to happen; prosperity pursues faithful people.
People often focus their attention and faith on prosperity. Though the Bible promises prosperity, it was not promised for self-indulgence. Prosperity is part of the covenant-pact between Yahweh and Abraham. People who walk in the faith of Abraham receive abundant blessings.
Prosperity is something spiritual that manifests in the natural realm. Prosperity is a picture of life, but poverty of death. Prosperity is a picture of heaven, and poverty of hell. Prosperity is a picture of blessing, poverty of curse. The Kingdom of God is an immensely prosperous place/realm. People who abide in Jesus Christ have a share in that prosperity.
Jesus commanded His disciples to live by faith, and not from the overflow of their accumulated possessions. People should love people and use possessions, not the other way around.
"But seek first his kingdom and his righteousness, and all these things will be given to you as well." (Matthew 6:33 NIV)
