Giving is an act of worship. Paul writes, in 2 Corinthians 9:6-8 –
Now this I say, he who sows sparingly will also reap sparingly, and he who sows bountifully will also reap bountifully. Each one must do as he has purposed in his heart, not grudgingly or under compulsion, for God loves a cheerful giver. And God is able to make all grace abound to you, so that always having all sufficiency in everything, you may have an abundance for every good deed…
Here we see the principle of sowing and reaping, the purpose of the individual heart, and the promise of God to supply.
May the Lord richly supply as you worship Him with what you have purposed in your heart.
