If you think that you've got all you need. Then, you are expected to give thanks to God almighty. Because, he gave you all that you have presently (James 1 : 17) and he did give them to you including your riches/affluence/fortune for a purpose i.e. to share them with all and sundry. But, on the other hand, if you think that you've not yet gotten all you need. Then, feel free to approach/ask God for them via prayers. For, he promised to supply all your needs according to his riches in glory (Philipians 4 : 19).
