Hi Aineo!
Yes, God does require offeribgs. However, since He has seen fit to punish us by temporarily taking away the offerings, we are forced to make do with prayer, repentance & charity. Hosea endorses this approach when he says:
Return, O Israel, unto the Lord your God; for you have stumbled in your iniquity. Take with you words, and return unto the Lord; say unto Him: 'Forgive all iniquity, and accept that which is good; so will we render for bullocks the offering of our lips.
The Torah does mention other ways of effecting atonement & given the temporary absence of the offerings, we rely on those until the offerings are restored.
Thanks for the Chronicles citation.
Be well!
