I willingly give back to God from the bounty with which He has blessed me

1 Chronicles 29:14-17

But who am I, and what is my people, that we should be able to offer so willingly as this? For all things come from you, and we have given you of your own. For we are strangers before you, and foreigners, as all our fathers were. Our days on the earth are as a shadow, and there is no remaining. The LORD our God, all this store that we have prepared to build you a house for your holy name comes from your hand, and is all your own. I know also, my God, that you try the heart, and have pleasure in uprightness. As for me, in the uprightness of my heart I have willingly offered all these things. Now I have seen with joy your people, who are present here, offer willingly to you.
