Let those who favor my righteous cause and have pleasure in my uprightness shout for joy and be glad and say continually, Let the Lord be magnified, Who takes pleasure in the prosperity of His servant.  Psalm 35:27 AMP

There can be no doubt, from the scripture, that Father God wants to bless and prosper His children. The reason more of them are not blessed is either because of lack of knowledge of God’s word or because of failure to act on the word which they know. Hosea 4:6 AMP says, “My people are destroyed for lack of knowledge,” and Matthew 7:26 AMP says that, “everyone who hears these words of Mine and does not do them will be like a stupid (foolish) man who built his house upon the sand.”  James 1:22-25 NKJV says, “But be doers of the word, and not hearers only, deceiving yourselves. For if anyone is a hearer of the word and not a doer, he is like a man observing his natural face in a mirror; for he observes himself, goes away, and immediately forgets what kind of man he was. But he who looks into the perfect law of liberty and continues in it, and is not a forgetful hearer but a doer of the work, this one will be blessed in what he does.”

The Lord instructed Joshua to meditate on God’s word and do it and He promised him that EVERYTHING he did would prosper. This promise was not just for Joshua, but for us as well. 

No man shall be able to stand before you all the days of your life; as I was with Moses, so I will be with you. I will not leave you nor forsake you. 6 Be strong and of good courage, for to this people you shall divide as an inheritance the land which I swore to their fathers to give them. 7 Only be strong and very courageous, that you may observe to do according to all the law which Moses My servant commanded you; do not turn from it to the right hand or to the left, that you may prosper wherever you go. 8 This Book of the Law shall not depart from your mouth, but you shall meditate in it day and night, that you may observe to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success.  Joshua 1:5-8 NKJV

Therefore keep the words of this covenant and do them, that you may deal wisely and prosper in all that you do.  Deuteronomy 29:9 AMP

Meditate on these promises below, and then set your heart to obey God so that you too may prosper in everything you undertake:

And the Lord your God will make you abundantly prosperous in every work of your hand, in the fruit of your body, of your cattle, of your land, for good; for the Lord will again delight in prospering you, as He took delight in your fathers, 10 If you obey the voice of the Lord your God, to keep His commandments and His statutes which are written in this Book of the Law, and if you turn to the Lord your God with all your [mind and] heart and with all your being.  Deuteronomy 30:9-10 AMP

And the Lord shall make you have a surplus of prosperity, through the fruit of your body, of your livestock, and of your ground, in the land which the Lord swore to your fathers to give you. 12 The Lord shall open to you His good treasury, the heavens, to give the rain of your land in its season and to bless all the work of your hands; and you shall lend to many nations, but you shall not borrow.
Deuteronomy 28:11-12 AMP

The Lord makes poor and makes rich; He brings low and He lifts up. 8 He raises up the poor out of the dust and lifts up the needy from the ash heap, to make them sit with nobles and inherit the throne of glory. For the pillars of the earth are the Lord’s, and He has set the world upon them.
1 Samuel 2:7-8 AMP

Both riches and honor come from You, and You reign over all. In Your hands are power and might; in Your hands it is to make great and to give strength to all.
1 Chronicles 29:12 AMP

For I was ashamed to request of the king a band of soldiers and horsemen to protect us against the enemy along the way, because we had told the king, The hand of our God is upon all them for good who seek Him, but His power and His wrath are against all those who forsake Him.  Ezra 8:22 AMP

If they obey and serve Him, they shall spend their days in prosperity and their years in pleasantness and joy. 
Job 36:11 AMP

The LORD is my shepherd; I shall not want. 
Psalms 23:1 KJV

The Lord is my Shepherd [to feed, guide, and shield me], I shall not lack.  Psalms 23:1 AMP

O fear the Lord, ye his saints: for there is no want to them that fear him. 10 The young lions do lack, and suffer hunger: but they that seek the Lord shall not want any good thing.  Psalms 34:9-10 KJV

I have been young and now am old, yet have I not seen the [uncompromisingly] righteous forsaken or their seed begging bread. 26 All day long they are merciful and deal graciously; they lend, and their offspring are blessed. 
Psalms 37:25-26 AMP

Blessed be the Lord, who daily loadeth us with benefits, even the God of our salvation. Selah.  Psalms 68:19 KJV

For the Lord God is a sun and shield: the Lord will give grace and glory: no good thing will he withhold from them that walk uprightly. Psalms 84:11 KJV

Bless the Lord, O my soul; And all that is within me, bless His holy name! 2 Bless the Lord , O my soul, And forget not all His benefits: 3 Who forgives all your iniquities, Who heals all your diseases, 4 Who redeems your life from destruction, Who crowns you with lovingkindness and tender mercies, 5 Who satisfies your mouth with good things, So that your youth is renewed like the eagle’s.  Psalms 103:1-5 NKJV
