II Corinthians 9

“He who sows sparingly shall also reap sparingly, and he who sows bountifully shall also reap bountifully” (v6).  Paul was encouraging the Corinthian believers to keep giving cheerfully, “not grudgingly or under compulsion” (v7).  He was also teaching them to invest their efforts and resources generously, whatever they did, believing that “having all sufficiency in everything, you may have an abundance for every good deed” (v8). 

This confidence, the opposite of anxiety, is only possible when we believe that God Himself “will supply and multiply [our] seed for sowing and increase the harvest of [our] righteousness” (v10).
