I do not care that much about prosperity. I have learned to be content with what I have and praise God, so I am not looking for an argument. But there are points that have to be made, and let's not reject scripture just so we can pile on prosperity teachers. And yes, there are many believers who need to trust God for the well-being of their families. Some believers are in poverty and have serious needs. So, let's take care not to discourage them from believing God for their needs.
Scriptures give us reason to believe in God's all-sufficient supply. I will rest on these.

The Lord is my shepherd; I shall not want.

Psalm 145:8-9
The Lord is gracious and full of compassion, slow to anger and great in mercy. The Lord is good to all, and His tender mercies are over all His works.
Proverbs 3:9-10

Proverbs 8:17-21
I love those who love me, and those who seek me diligently will find me. Riches and honor are with me, enduring riches and righteousness. My fruit is better than gold, yes, than fine gold, and my revenue than choice silver. I traverse the way of righteousness, in the midst of the paths of justice, that I may cause those who love me to inherit wealth, that I may fill their treasuries.
Proverbs 10:2-6
Treasures of wickedness profit nothing, but righteousness delivers from death. The Lord will not allow the righteous soul to famish, but He casts away the desire of the wicked. He who has a slack hand becomes poor, but the hand of the diligent makes rich. He who gathers in summer is a wise son; he who sleeps in harvest is a son who causes shame. Blessings are on the head of the righteous, but violence covers the mouth of the wicked.

He who gives to the poor will not lack, but he who hides his eyes will have many curses.

As for every man to whom God has given riches and wealth, and given him power to eat of it, to receive his heritage and rejoice in his labor—this is the gift of God.
Isaiah 1:19
If you are willing and obedient, you shall eat the good of the land.
Isaiah 58:10-11
If you extend your soul to the hungry and satisfy the afflicted soul, then your light shall dawn in the darkness, and your darkness shall be as the noonday. The Lord will guide you continually, and satisfy your soul in drought, and strengthen your bones; you shall be like a watered garden, and like a spring of water, whose waters do not fail.
Jeremiah 17:7-8
Blessed is the man who trusts in the Lord, and whose hope is the Lord.

Hebrews 7:19-22
For the law made nothing perfect; on the other hand, there is the bringing in of a better hope, through which we draw near to God. And inasmuch as He was not made priest without an oath (for they have become priests without an oath, but He with an oath by Him who said to Him: “The Lord has sworn and will not relent, ‘You are a priest forever according to the order of Melchizedek’”), by so much more Jesus has become a surety of a better covenant.
Hebrews 11:6
But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.
