The apostle Paul is writing about giving in 2 Corinthians 9.  (Please read the whole chapter.)
 
In verses 6-7 there is the principle of giving’
“But this I say: He who sows sparingly will also reap sparingly, and he who sows bountifully will also reap bountifully.
So let each one give as he purposes in his heart, not grudgingly or of necessity; for God loves a cheerful giver.”
 
Vs. 8 goes on to say,
“And God is able to make all grace abound toward you, that you, always having all sufficiency in all things, may have an abundance for every good work.”
 
Then in Proverbs 11:24-25.
“There is one who scatters, yet increases more;
   And there is one who withholds more than is right,
   But it leads to poverty.
The generous will be made rich,
   And he who waters will also be watered.”
 
The title of Psalm 112 in my NKJV Bible is ‘The Blessings of Those Who Fear God”
“He has dispersed abroad,
He has given to the poor;
His righteousness endures forever;
His horn (dignity) will be exalted with honor.”  Vs. 9
 
For want of a better word, the ‘formula’ for giving we see in 1 Corinthians 16:1-2, 
“Now concerning the collection for the saints, as I have given orders to the churches of Galatia, so you must do also;
On the first day of the week let each one of you lay something aside, storing up as he may prosper, that there be no collections when I come.”
 
These collections were for Christians who were sorely in need when the churches were being established during Paul‘s missionary journeys.  
Read Acts 20 for a taste of one of his mission journeys.  The verses of this chapter tell us how much this great apostle was loved.
But we, too, love him centuries later!  His God inspired letters are as 2 Timothy 3:16-17 were meant for all Believers.
“All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work.”
 
Believers, remember Whose you are!
“For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.”  Ephesians 2:10
 
As Paul exhorts the Thessalonians and us,
“See that no one renders evil for evil to anyone, but always pursue what is good both for yourselves and for all,
Rejoice always,
pray without ceasing,
in everything give thanks; for this is the will of God in Christ Jesus for you. 
Do not quench the Spirit.
Do not despise prophecies.
Test all things; hold fast what is good.
Abstain from every form of evil.”  1 Thessalonians 5:15-22
 
Thank you Lord for your Word and the teachers you have provided to open it up to us.  Our desire is to know you and your ways more and more.  All praise and glory are yours.  Amen
